What materials form Metamorphic Rocks?
Metamorphic rocks can form from the transformation of pre-existing rocks under high temperatures and pressures. Common parent rocks include shale, limestone, and granite. The minerals present in the parent rocks determine the types of metamorphic rocks that can form.
Are andalusite sillimanite and kyanite sedimentary rocks?
No, andalusite, sillimanite, and kyanite are not sedimentary rocks. They are metamorphic minerals that form under high-pressure and high-temperature conditions from the metamorphism of aluminum-rich rocks like schist or pelitic rocks.
Which phenomenon leads to the formation of metamorphic rocks?
Metamorphic rocks are formed when existing rocks undergo intense heat, pressure, or chemical changes within the Earth's crust. These changes cause the minerals in the rocks to reorganize and form new structures, resulting in the creation of metamorphic rocks.
