But there is no evidence. And there are debates.

Granite batholiths...........


"However, this long-accepted timescale for these processes is now being challenged, even by conventional geologists (Clemens 2005; Petford et al. 2000). The essential role of rock deformation is now recognized. Previously accepted granite formation models required unrealistic deformation and flow behaviors of rocks and magmas, or they did not satisfactorily explain available structural or geophysical data. Thus it is now claimed that mechanical considerations suggest granite formation is a “rapid, dynamic process” operating at timescales of less than 100,000 years, or even only thousands of years.

Material deposited by groundwater in cracks in rocks forms





veins


dikes


batholiths


stalactites|||Veins.


I got this copy from Wikipedia. My very first Wiki copy on Y!A. (the key word is cracks (fissures))





"In geology, a vein is a finite volume within a rock, having a distinct shape, filled with crystals of one or more minerals, which were precipitated from an (aqueous) fluid. Veins are formed by fluids carrying mineral constituents into a rock mass as a consequence of some form of hydraulic flow within the rock. Usually this is the result of hydrothermal circulation.





Veins are classically thought of as being the result of growth of crystals on the walls of planar fractures in rocks, with the crystal growth occurring normal to the walls of the cavity, and the crystal protruding into open space.





This certainly is the method for the formation of some veins. However, it is rare in geology for significant open space to remain open in large volumes of rock, especially several kilometers below the surface. Thus, there are two main mechanisms considered likely for the formation of veins: open-space filling and crack-seal growth."

Here's another geologic cite reference:

wiki: "Stalactites are formed by the deposition of calcium carbonate and other minerals, which is precipitated from mineralized water solutions. Limestone is calcium carbonate rock which is dissolved by water that contains carbon dioxide, forming a calcium bicarbonate solution."

Help with Earth Science? (Rocks)?

My question is





"Select the rock type most likely to form in each situation"


Andesite, Granite, Diorite, Basalt, Peridotite, Gabbro, Rhyolite





A. Silicic magma cooling slowly in a batholith


B. Mafic magma cooling rapidly in a dike


C. Intermediate magma cooling slowly in a stock


D.Low-silica magma cooling slowly in the mantle


E. Silicic magma cooling quickly near the surface.








I give up, Ive come up with several answers because I always pick 1 rock that I think can fit in 2 of those...so can someone answer this for me?|||Andesite and Rhyolite are extrusives and can be excluded in this question. Basalt is generally an extrusive but can also be applied to shallow intrusives as well.





A. Granite: silica bearing, large-grained=slow cooling in batholith/pluton


B. Diorite: fine-grained=rapid cooling


C. Gabbro: intermediate grained larger than diorite


D. Peridotite: a classic felsic, deep crust/upper mantle and low in silica)


E. Basalt|||use your Earth Science Reference Tables|||A- Granite, It has a high silica content and the large crystals are characteristic of slow cooling.


B- Basalt, there is nothing else in that list which is mafic and contains sufficiently small crystals. Someone mentioned diorite which is coarse grained and therefore the wrong answer.


C- Diorite, Coarse grained (slow cooled) and of intermediate composition. Gabbro is most certainly not the correct answer as it is basic not intermediate.


D- Peridotite, It's the only one on the list which forms in the mantle.


E- Rhyolite, I will show why by saying why it can't be any of the others:


- Andesite cools relatively quickly but is intermediate.


- Granite is silicic but cools slowly.


- Diorite cools too slowly and is intermediate.


- Basalt cools quickly but is basic, not silicic.


- Peridotite forms too deep.


- Gabbro is a basic composition and it cools too slowly.


The only one it can therefore be is rhyolite which fits both criteria of being silicic and rapidly cooled.

Latent Heat of Fusion Question?

Im currently doing revision for a Maths Resit by doing a couple of past papers. Now Ive come accross a question in the paper that I cant work out how to answer, even after looking through all my notes. Its a multiple part question but the bit I cant do is:





If the Latent heat of fusion is 4.5x10^5 how much heat is released as it solidifies?


You also need to know that we are talking about a granitic batholith with a volume of 240000 a density of 2500 and a mass of 600,000,000.





I dont want the answer but the equation to work it out for myself :)


Thanks|||You are missing units for all the numbers, so I can't give you an answer. But I can show you how.



Dimensional analysis will solve a lot of these problems for you. Here is an example:



How much energy does it take to freeze 3 kg of water?

heat of fusion of ice is 334 kJ/kg

Energy in kJ = 334 kJ/kg x 3 kg

notice how the kg's cancel leaving the kJ units.

Choose basaltic or granite


1. ___ contains a low percentage of silica


2. ___ has high viscosity


3. ___ contains a high percentage of silica


4. ___ has low viscosity


5. ___ flows quietly without explosive eruptions


6. ___ traps gases and produces explosive eruptions

11. Magma is forced into a crack that cuts across rock layers. ____


12. Magma is forced into a crack parallel to rock layers. ____


14. A mass of think, highly viscous lava piles up instead of flowing freely. ____|||10.Places where plates are coming apart are called divergent boundaries. As the plates separate along the boundary, the block between the faults cracks and drops down into the soft, plastic interior (the asthenosphere). The sinking of the block forms a central valley called a rift. Magma (liquid rock) seeps upward to fill the cracks. In this way, new crust is formed along the boundary. Earthquakes occur along the faults, and volcanoes form where the magma reaches the surface.





11.formed by plate tectonics as an oceanic tectonic plate subducts under another tectonic plate and produces magma.





12.There are two ways in which a group of islands can form.


a.) As a lithospheric slab is being subducted, the slab melts when the edges reach a depth which is sufficiently hot. Hot, remelted material from the subducting slab rises and leaks into the crust, forming a series of volcanoes. These volcanoes can make a chain of islands called an "island arc". Examples of island arcs are the Japanese islands, the Kuril Islands, and the Aleutian Islands of Alaska, shown here.


Island Arcs are formed on the opposing edge of a subducted slab. For each case, there is an associated subducting slab and a trench.


b) The second way in which islands are formed is via plumes or hot spots in the lithosphere. The Hawaiian Islands are an example of this type of island formation. In this case, there is no associated subducting slab.

2. C





3. B





True.....To an extent. Aphanitic is not a synonym for volcanic, however most volcanic rocks have an aphanitic texture. The term aphanitic describes the texture of the rock. The term volcanic means it erupts at the Earth's surface. The answer to this question really depends on how sophisticated and knowledgeable your teacher is who made it up.

Volcano Questions...?

i cant find the answer to these, please help





1)Which type of landform develops at plate boundaries where one oceanic plate descendes beneath another?


a) rift valley


b) lava plateau


c) volcanic island arc


d) mountain ranges frmed by batholith











2) Most intraplate volcanic activity occurs where ____.


a) hot mantle plumes rise toward the surface within a plate.


b) oceanic plate diverge


c) hot magma descends into the mantle under a plate


d) oceanic and continental plates converge.|||1) (c) volcanic island arc





When an oceanic plate is forced beneath another into the Earth, it is called subduction. The descending (subducting) plate displaces magma from the mantle and forces it upwards, resulting in a deep-ocean trench and an arc of volcanoes (which are your volcanic islands) on the upper (overriding) plate along the trench.





2) (a) hot mantle plumes rise toward the surface within a plate





First of all, "intraplate" means "within a plate", so the answer cannot be (b) or (d), as those occur at plate boundaries. For (c), this does not ordinarily happen, as hot magma is less dense than the crust and surrounding mantle (which is why it rises in the first place). Now as for the correct answer (a), this is what is known as a hotspot, where unusually hot magma rises up through a plate, causing volcanism on the plate surface. The plate moves over the stationary mantle plume, creating a trail of evidence of volcanic activity. Examples include the Hawaiian Islands and Yellowstone.

Answers the following questions? 15 points?

1. The process of isostatic adjustment is most closely associated with which of the following?





a. sea-floor spreading





b. buoyancy





c. volcanic activity





d. lithospheric plate collision





2.


If you were driving down the highway and saw mountains composed of layered strata, you could be confident that you were looking at











a. batholiths or laccoliths.





b. a shield volcano.





c. extrusive igneous rock.





d. sedimentary rocks.|||1) Isostatic Adjustment is most closely related to B: Buoyancy. "Isostasy is the principle of buoyancy where an object immersed in a liquid is buoyed with a force equal to the weight of the displaced liquid. On a geological scale, isostasy can be observed where the Earth's strong lithosphere exerts stress on the weaker asthenosphere which, over geological time flows laterally such that the load of the lithosphere is accommodated by height adjustments."





2) You would be looking at D: sedimentary layers. Sedimentary layers for well defined strata for the most part, unless it is extremely weathered. The strata are a result of different deposition events that lay the sediment in place and then another deposition event comes about and deposits another layer on top of that.





The sources I cited should clarify things pretty well.


Hope you find this helpful.





It wouldn't be batholith's since they are just large igneous intrusions which do not form well defined bed sets. The same thing goes for extrusive igneous rocks.It also would not be a shield volcano because they are built mainly from lava flows which also exhibit poor bedding.

a. laccolith


b. crater


c. plate boundary


d. batholith|||c plate boundary because it is where magma would be close enough to the surface to get exposed therefore making a volcano|||C. plate boundary because plate boundaries such as divergent boundaries at mid ocean ridges can cause land to split and form volcanoes underwater.

Anyone know the answers to these geology questions?

1. While working in the field, you find a dike cutting across some sedimentary rocks. What grain size would you expect to find in this pluton?





glass


fine-grained


aa


coarse-grained


nonfoliated





2. Batholiths are known to form the cores of mountain ranges such as the Sierra Nevada. What is the implication of this observation?





Because the batholith is at the surface, it implies close proximity to a transform boundary.


Because batholiths form deep within Earth, the occurrence of one at the surface implies that it has since been uplifted and/or the rocks above have been removed.


Because the batholith is exposed at Earth鈥檚 surface, it implies an effusive or quiescent eruption.


Because the batholith is at the surface, it implies close proximity to a divergent zone.


Because the batholith is at the surface, it implies that the magma in it cooled quickly.|||I would say fine grained for the first one, but im not entirely sure if you mean the dike or the sedimentary rock. But Im going with the dike. One that it is in sedimentary rocks which have not been altered which means they must be somewhat close to the surface. So the dike would be close to the surface which means it would have cooled somewhat rapidly and begun to form small crystals so small grained.





the second one is the second one because inorder for something that formed deep within the earth to be at the surface some form of weathering and/or uplift must have occured.

Three volcano questions, please help I've been working on this project for 5 hours now.?

lava with high amounts of granite usually forms


a- explosive, gaseous volcanoes


b- non-explosive, quiet lava flows


c- shield volcanoes


d- magma that is high tn basalt





In the late 1800's , an island volcano in Indonesia, Krakatoa, erupted explosiveley. what kind of lava did the volcano erupt?


a- basaltic


b- granitic


c- silicic


d- magmic





If a volcano does not form at a hot spot, it must form at a


a- laccolith


b- crater


c- plate boundary


d- batholith|||For the first question, granite doesn't erupt, it's an intrusive/plutonic rock type. Assuming what's really meant is rhyolite, granite's extrusive/volcanic counterpart, the answer is A, explosive, gaseous volcanoes. Shield volcanoes, such as the one I live on (Mauna Loa) are not made of granite/rhyolite and basalt is a type of magma not something a magma can be high in so C and D are out. B is not the correct answer because granite/rhyolite is a silicic magma and they don't erupt quietly.





For question two, the answer is C, silicic because silicic magma (such as rhyolite) erupts explosively. Basaltic lava erupts effusively, granite doesn't erupt as I already mentioned, and magmic isn't a type I've ever heard of.





For question three, the answer is C, a plate boundary. Laccoliths and batholiths are both types of intrusive magma bodies and a crater is a depression feature (sometimes associated with volcanic activity, but not always), so those are not places volcanoes form.|||1: a





2: a ?





3: c|||i dont know the first two without contacting the very back of my mind, but the last one is "c". good luck on your project.|||c c, and a. just studied that stuff.|||I can assure you that the first answer is most definitely A. Granitic magma has a high viscosity (due to it's lower temperature and higher silica content) that traps a lot of gas, when this gas reaches the low pressures of the surface it explodes out making for violent and destructive eruptions.





Answer two I can't tell you with 100% certainty, but it is safe to assume that Krakatoa erupted felsic (granitic) magma. Basaltic eruptions are usually not violent and are not associated with pyroclastic flows - Krakatoa's 1883 eruption is the most violent eruption in modern times and ejected huge volumes of gas and ash these are not typical of a basaltic volcano. Magmic is not a word so you can discount that answer. The answer is either B or C -- as granite is a silicic rock (silica rich rock). If I had to choose I would go with C, just because I do not know exactly what kind of magma Krakatoa erupted, but I'm sure it had a high silica content.





As for the last question... The answer is C.





edit: The answer after me is 100% correct, granite is an intrusive rock, and is never erupted (something I stupidly failed to remember) - so definately go with C for question two. In question one, what it could mean is magma that has melted and mixed with large amounts of granite, not that the lava itself is going to form granite -- otherwise, as the answer after mine says, it should say rhyolite which is the extrusive equivalent of granite.|||number three is most def c.......

Help with a Batholite question?

i have a question for homework that says describe the developments of a Batholith. i don't know how to answer it or what it means. please help|||A batholith is a large body of igneous rock. In very basic terms of development they are emplaced in liquid form, ie a magma, within 'country rock' and crystallise (to be seen at surface erosion has to have occurred.





In more complex terms, batholiths are made up of a number of smaller plutons of igneous rocks that have risen in molten form through the 'country rock' by pushing the colder, more dense material aside and/or partial melting. Chemically they tend to be felsic or intermediate in composition. Crystallisation does not occur all at the same time and therefore different rock types will be present within a batholith. Early stages tend to be finer grained and less felsic, late stages tend to coarse (even pegmatitic) and more felsic.





In economic terms batholiths can be used for there stone content (aggregate etc) but may also be host to gold, tin, wolfram and other in-compatible elements close to, at or just outside the contact zone with the host rock.





good luck

Are you good at science?

i need help with science. can u describe the words batholith, volcanic neck, dike, n sill? thanx if u do|||A batholith (from Greek bathos, depth + lithos, rock) is a large emplacement of igneous intrusive (also called plutonic) rock that forms from cooled magma deep in the earth's crust. Batholiths are almost always made mostly of felsic or intermediate rock-types, such as granite, quartz monzonite, or diorite





A volcanic neck is a cylindrical-shaped landform standing above the surface created by magma solidifying in the vent of a volcano. Erosion of the sides of the volcano exposes the neck.





A dike or dyke in geology is a type of sheet intrusion referring to any geologic body that cuts discordantly across





* planar wall rock structures, such as bedding or foliation


* massive rock formations, like igneous/magmatic intrusions and salt diapirs.





Dikes can therefore be either intrusive or sedimentary in origin.





In geology, a sill is a tabular pluton that has intruded between older layers of sedimentary rock, beds of volcanic lava or tuff, or even along the direction of foliation in metamorphic rock. The term sill is synonymous with concordant intrusive sheet. This means that the sill does not cut across preexisting rocks, in contrast to dikes, which do cut across older rocks.


Illustration showing the difference between a dike and a sill.





Sills are always parallel to beds (layers) of the surrounding country rock. Usually they are in a horizontal orientation, although tectonic processes can cause rotation of sills into near vertical orientations. They can be confused with solidified lava flows; however there are several differences between them. Intruded sills will show partial melting and incorporation of the surrounding country rock. On both the "upper" and "lower" contact surfaces of the country rock into which the sill has intruded, evidence of heating will be observed (contact metamorphism). Lava flows will show this evidence only on the lower side of the flow. In addition, lava flows will typically show evidence of vesicles (bubbles) where gases escaped into the atmosphere. Because sills generally form at depth (up to many kilometers), the pressure of overlying rock prevents this from happening much, if at all. Lava flows will also typically show evidence of weathering on their upper surface, whereas sills, if still covered by country rock, typically do not|||Yes, I'm good at science.

D) monocline|||batholith





A batholith (from Greek bathos, depth + lithos, rock) is a large emplacement of igneous intrusive (also called plutonic) rock that forms from cooled magma deep in the Earth's crust. Batholiths are almost always made mostly of felsic or intermediate rock-types, such as granite, quartz monzonite, or diorite (see also granite dome).

thankkk you if you can help :)|||Find the one that will yield more granite. I think sill will be more easy to extract due to its more straight characteristics. while Batholith may have a lot of irregular dimensions. Which one is easier to query. Batholith due to its shape might also yield more granite so either way figure out which is easier to query and which will yield more rock|||i vote for batholith

The most widespread of all intrusive forms is the?

a. batholith


b. lava flow


c. volcano


d. dike


e. stock|||I suppose widespread means "can be found the most diverse places" in which case I would say dike. Dikes seem to occur pretty well everywhere. If widespread means "areally extensive (cover the most area)", I suppose I would say batholiths. really not a matter of great importance. just spit back whatever the book or the prof or the teacher said.|||Bad question, Dike is probably the answer required as numerically this form is most common however dikes tend to be narrow though they can be pretty long (tens to a few hundred Km)


Batholiths can be pretty big, they can be regional features


Lava flows are Extrusive, not Intrusive as are Volcanos

Which of the following is not exogenic in nature?

A. batholith formation


B. mass wasting


C. erosion


D. weathering|||Hmm...tricky.





Erosion is definately exogenic as is weathering. Mass wasting would be considered exogenic as well as it is merely the downwards movement of materials via gravity and slope, and the erosion needed to uncover the batholith is exogenic.





HOWEVER, the magma and cooling of the magma is endogenic, so I would have to go with A.








Hope it helps|||B. mass wasting

Please help me with this science question?????

here is the question:





what rock formation is better to mine granite from??


a batholith or a sill, considering that they have the same plutonic depth.





i really need help! thank you if you can help. legit answers only, PLEASE!!|||I would say a batholith. Batholiths are composed of a huge expanse of granitic rock %26amp; are the largest intrusive igneous bodies. They usually form the core of mountain ranges (ie- the mountain IS a batholith, therefore lots of granite). In the case of an exposed batholith (a mountain), the surrounding rock has already been removed by uplift %26amp; erosion. Batholiths can extend several miles into the crust.





A sill is formed when basaltic magma is injected horizontally into already existing sedimentary layers, lifting the sedimentary layer of rock up (like an underground lava flow forcing its way in between softer sedimentary rock %26amp; then solidifying). Sills only form at shallow depths %26amp; are smaller than batholiths.

Stumped on a geology question?

Geologists generally agree that batholiths are emplaced by forceful injection.





True or False?|||When gigantic batholiths are intruded, the surrounding rock, known as the country rock, must somehow make room for the intrusion. Several models have been suggested, but most geologists now agree that a mechanism known as forceful injection is probably responsible for emplacement. Apparently, as the body of magma rises, it deforms the country rock, pushing it out of the way.
