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.
One of the most common igneous rocks is granite (Figure 4.9). Granite is used extensively in building materials and making statues. Perhaps you have used a pumice stone to smooth your skin or to do jobs around the house.Pumice is another example of an igneous rock (Figure 4.10).ecause such slow cooling allows time for large crystals to form, intrusive igneous rock has relatively large mineral crystals that are easy to see.
