Examples of gemstones that are found within igneous rocks as a secondary deposit include amethyst, larimar, and fire opal. Metamorphic Rocks Metamorphic rocks form when existing rocks are subjected to intense pressure and/or temperature increases that lead to the alteration of the rocks mineralogical composition, texture, and structure.
The word igneous comes from the Latin for fire, and what igneous rocks have in common is that they formed by the cooling and crystallization of a melt. This material may have been lava erupted at the Earth's surface, or magma (unerupted lava) at depths of up to a few kilometers, or magma in deeper bodies (plutons).ranite is the light, coarse-grained rock formed at depth and exposed after deep erosion. It is rich in feldspar and quartz (silica) and hence is called a felsic rock. So granite is felsic and plutonic. Basalt and granite account for the great majority of igneous rocks.
