metamorphic minerals

Metamorphic minerals are minerals that form under high pressure and temperature conditions within the Earth’s crust, transforming existing rocks into new types. These conditions cause minerals to change their structure without fully melting the rock. Common metamorphic minerals include garnet, staurolite, and kyanite. They often develop in rocks like limestone or shale during mountain-building processes or deep burial. These minerals help geologists understand the history of rock formation and the environmental conditions during metamorphism. Essentially, they are the signatures of rocks that have undergone deep, intense changes deep beneath the Earth’s surface.
