* Marble: This is the most common metamorphic rock derived from limestone. It forms under moderate to high temperatures and pressures, often accompanied by the recrystallization of calcite, the main mineral in limestone. Marble is known for its beautiful veining and is often used in construction and sculpture.
* Skarn: This rock forms when limestone interacts with other rocks, usually igneous intrusions, during the metamorphic process. Skarn is often rich in minerals like garnet, pyroxene, and epidote, giving it a characteristic appearance.
* Calc-silicate rock: This rock forms when limestone is metamorphosed in the presence of silica-rich fluids, resulting in the formation of minerals like wollastonite, diopside, and tremolite. Calc-silicate rocks can be found in metamorphic belts associated with mountain building.
Other less common metamorphic rocks derived from limestone include:
* Hornfels: A dense, fine-grained rock formed under high temperatures but low pressures.
* Eclogite: A rare rock formed under extremely high pressures, often containing garnet and omphacite.
The specific rock that limestone transforms into depends on the specific conditions of metamorphism.
