What's the difference between pluton and batholith? and more?

what's the difference between:


felsic magma, mafic magma


cemetation, stratification











is it possible for rocks in the rock cycle to skip becoming sedimentary rocks?





how does the cooling rate of magma affect the formation of igneous rocks?





why are fossils more likely to be formed in shale and sandstones than in conglomerate?|||Felsic magma is rich in mostly Si, and also Al, K, and Na.


Mafic magma is rich in Fe, and Mg with lower values of Si





Cementation is when pore space is filled in when water seeps through and precipitates.





Stratification is the layering of rocks. Generally older rocks are on bottom and younger on top. This is change whenever something alters it, like mountain building.





Not all rocks are sedimentary at any stage of their life. Sedimentary rocks are formed from igneous, metamorphic, and other sedimentary rocks. If a rock is weathered and the material never gets compacted and lithified, then it will not become sedimentary.





The cooling rate affects the size of minerals in igenous rocks. If a magma cools slowly, the crystals have a longer time to grow and can become larger. If it cools fast then the crystals can be smaller.





The difference of where fossils are found would go back to the type of environment that those rocks were formed in. Shales and Sandstones are in a less energetic environment.. more so shales. Conglomerates form in a higher energy environment. Fossils need to be at rest when covered and this just wouldn't allow it. Also, shales form from softer sediments than conglomerates. Conglomerates are pieces of rocks lithified together.





I hope this helped!|||A pluton is any body of igenous rock that has solidified in the subsurface. A batholith is a deep-rooted pluton with an exposure area of at least 40 square miles.





Felsic magma has a large percentage of quartz and feldspar; mafic magma consists mostly of dark minerals containing iron and magnesium. The slower the cooling rate of the magma, the larger the grain size of the igneous rock that results - everything else being equal.





Conglomerates are formed in high energy environments, where the remains of living organisms are likely to be crushed rather than preserved.





Cementation is the process of minerals being deposited in the interstices between grains, binding the grains to one another. Stratification is the deposition of rocks into layers.





I am no expert on the rock cycle but would say that it's possible to skip the sedimentary phase - igneous rocks can be metamorphosed.
