This results in the formation of new minerals and changes in the texture and structure of the original rock. Unlike igneous processes, whereby the rock becomes molten as magma, all metamorphic changes occur in solid rock. The most commonly known metamorphic rocks are marble (transformed limestone) and slate (transformed mudstone).

Corals, shellfish, algae, and other organisms secrete large amounts of calcium carbonate in their skeletal debris, forming the limestone deposit. Trace elements of sand, silt and clay are also often found in this type of limestone.
