What geologic processes are implied if granitic body of rock is found exposed at the surface?

Answer 1

Here are some things that may apply: 1) since granite is an intrusive igneous rock, the granite was not originally exposed at the ground surface, 2) since the granite was not originally exposed at the surface, there must have been a cause for its exposure, 3) the cause of the exposure could have been from uplift of the granite as material above was eroded, or 4) simple erosion of the material above the granite, 5) erosional factors could include river erosion, chemical weathering, glacial erosion, wind erosion, freeze-thaw cycles and other means, and finally, 6) the presence of granite is an indication that the site once experienced an intrusion of granitic magma from the melting of crustal material.

Answer 2

If a granitic body of rock is found exposed at the surface, it implies processes like erosion, uplift, and possibly faulting. The overlying rocks have been weathered and eroded away, exposing the granite. Uplift could have brought the granite closer to the surface, and faulting may have played a role in its exposure.
