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.
