* Marble: This is the most common metamorphic rock derived from limestone. It forms under relatively low pressure and temperature conditions, typically around 400°C. Marble is characterized by its distinctive interlocking calcite crystals, which give it a distinctive, often white and streaked appearance.
* Skarn: This is a metamorphic rock formed when limestone interacts with other minerals, like silica, iron oxides, or carbonates. Skarn is usually characterized by its complex mineral assemblage and often displays a distinctive colorful banding pattern.
* Calc-silicate rocks: These are formed under higher pressure and temperature conditions than marble. They are rich in calcium and silicate minerals, and their composition can vary depending on the specific minerals involved.
* Hornfels: This is a metamorphic rock formed when limestone is subjected to contact metamorphism, meaning it was heated by a nearby igneous intrusion. Hornfels is usually very hard and dense, and its color can range from grey to black depending on the minerals present.
So, in short, marble is the most common rock formed from the metamorphism of limestone, but several other interesting rocks can also be formed under different conditions.
