== == Mica is actually a group of silicate minerals, not classified as sedimentary, metamorphic, or igneous, although mica can appear in rocks of all three classifications. == ==
The three main types of rocks are igneous, formed from cooling lava or magma; sedimentary, formed from compressed layers of sediment; and metamorphic, formed from existing rocks that undergo high heat and pressure.
Graphite is a metamorphic rock. It is formed from the metamorphism of organic sedimentary rocks, such as coal, under high temperature and pressure.
The three types of rocks involved in the rock cycle are igneous rocks, sedimentary rocks, and metamorphic rocks. Igneous rocks form from the solidification of molten magma, sedimentary rocks form from the deposition and lithification of sediments, and metamorphic rocks form from pre-existing rocks that are subjected to high heat and pressure.

Aluminum is not classified as igneous, sedimentary, or metamorphic. It is a metallic element and is naturally found in the Earth's crust, often in combination with other elements or minerals.
