Porphyry. Porphyry is a type of igneous rock that is made up of large crystals of feldspar or quartz in a fine-grained matrix. This rock typically has a medium to dark color and is found in areas of volcanic activity.

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. These rocks include: andesite, basalt, dacite, obsidian, pumice, rhyolite, scoria, and tuff ... Igneous rocks from left to right: gabbro, andesite, pegmatite, basalt, pumice, porphyry, obsidian, granite, and tuff. Molten rock material below the surface is called magma. Magma that has reached the surface is lava.
