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.
Igneous rocks are formed from the solidification of molten rock material. There are two basic types. Intrusive igneous rocks crystallize below Earth's surface and the slow cooling that occurs there allows large crystals to form. Examples of intrusive igneous rocks are diorite, gabbro, granite, pegmatite, and peridotite. Extrusive igneous rocks erupt onto the surface where they cool quickly to form small crystals. Some cool so quickly that they form an amorphous glass.
