Types of Rocks

Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form". The original rock is subjected to heat with temperatures greater than 150 to 200°C and pressure around 1500 bars, causing profound physical and/or chemical change. ... Sandstone, limestone and marble ...

Limestone: The Calcium Carbonate Chemical Sedimentary Rock …

Marble is a carbonate rock, usually a marine limestone, that has been squeezed and deformed like plastic by great heat and pressure deep beneath the Earth's surface. This process is called "metamorphism." There are also rare "igneous" carbonate rocks that have crystallized from molten magma in the same way that lavas or granites have.

5.6: Metamorphism and Metamorphic Rocks

The parent rock is the rock that exists before metamorphism starts. As we see in the rock cycle, any type of rock can be a protolith including pre-existing metamorphic rock. The critical component of the parent rock is its mineral composition because it is the stability of each mineral that matters when metamorphism takes place.
