Intrusive Igneous Rocks (formed from magma below the surface):
* Granite: A coarse-grained rock with large crystals of quartz, feldspar, and mica. It is commonly used in building and construction.
* Diorite: A medium-grained rock with plagioclase feldspar and hornblende. It is often used as a decorative stone.
* Gabbro: A dark-colored, coarse-grained rock rich in pyroxene and plagioclase feldspar.
* Peridotite: A dense, dark-colored rock composed mainly of olivine and pyroxene. It is found in the Earth's mantle.
* Syenite: A medium-grained rock with alkali feldspar and hornblende.
Extrusive Igneous Rocks (formed from lava above the surface):
* Basalt: A dark-colored, fine-grained rock rich in pyroxene and plagioclase feldspar. It is the most common type of volcanic rock.
* Rhyolite: A light-colored, fine-grained rock rich in quartz and feldspar. It is often found in volcanic domes and flows.
* Andesite: A medium-colored, fine-grained rock with plagioclase feldspar and pyroxene. It is often found in volcanic arcs.
* Obsidian: A glassy, black rock that forms when lava cools quickly.
* Pumice: A light-colored, porous rock that forms when lava with trapped gas cools quickly.
* Scoria: A dark-colored, porous rock that forms when lava with trapped gas cools quickly.
Other Igneous Rocks:
* Pegmatite: A coarse-grained igneous rock with unusually large crystals.
* Kimberlite: A rare, deep-seated igneous rock that is known for containing diamonds.
These are just a few examples of the many different types of igneous rocks. The specific minerals present and the texture of the rock can vary depending on the composition of the magma or lava, the cooling rate, and other factors.
