Mica is a silicate mineral that is typically found in sheet form. It is characterized by its basal cleavage, which means that it splits along well-defined structural planes. It is flaky and shiny due to its crystalline structure.

Is mica extrusive or plutonic?

Mica is a mineral that can be found in both extrusive and plutonic igneous rocks. It is commonly associated with granite, a plutonic rock, where it forms as a result of slow cooling of magma. However, it can also occur in volcanic rocks, which are extrusive, where it crystallizes from lava that cools quickly. Thus, mica itself is not categorized as exclusively extrusive or plutonic; rather, it can be present in both types of igneous rocks.
