Some are andestite porphyry, andestite, anorthosite, and amphibole.
igneous rocks
Igneous rocks are rocks that form from the cooling of magma or lava, and "igneous" is derived from the Latin word for "fire." Examples of igneous rocks include basalt, granite, and pumice.

igneous
Sedimentary, igneous and metamorphic.
Igneous rocks are formed when rocks reach the melting point becoming magma, then the magma starts to cool and crystallizes to form igneous rocks. Metamorphic rocks are made when they come in contact with a mass of magma but does not melt providing the energy to drive chemical reactions that recrystallize minerals.
Rhyolititcen rocks.
Igneous rocks are formed by the solidification of molten materials.
To the people that are doing the "Rock Worksheet" the answer for problem #5 is in the paper but the answer is actually (what I put), "Another name for igneous rocks is the rock of fire."
Sedimentary rock can be made up partially of igneous clasts, but igneous rock is igneous rock.
Examples of igneous rocks are pumice, obsidian, basalt, and rhyolite.
Igneous, sedimentary, and metamorphic rocks are the three main types of rocks. Igneous rocks are formed from the cooling of molten rock, sedimentary rocks from the accumulation of sediment, and metamorphic rocks from the transformation of existing rocks under heat and pressure.
