Coarse grained Igneous rock:

It is a type of igneous rock that have slowly cool down, hence minerals got more time to enlarge.

Here, John found the rock that contain large crystals without any sign of alteration due to heat or pressure.

Therefore, the rock that John found is formed from hardened magma.

From the above statement, John can infer that the rock underwent metamorphism and also is not altered by heat or pressure.

Explanation:

Metamorphic rock is an igneous sedimentary rock and although when put through heat the rock becomes hot but does not alter its shape or melt. If the rock melts then it is only an igneous rock and not a sedimentary one.During metamorphism, the chemical and the mineral content of prolith are changed due to changes in the environment based on physical and chemical conditions.Even though the rocks remain solid, fluid is present between the macroscopic spaces.This gives "The Geologist" accurate information of what happens beneath the earth during the formation of mountains.Metamorphic rocks are like probes that go down the earth and comes back giving information of what happens underneath the surface.
