Serpentine is the green mineral in this rock known as serpentinite. Form of it when limestone buried deep in the older layers of earth s crust is subjected to heat and pressure from thick layers of overlying sediments. Metamorphism causes variable recrystallization of the original carbonate mineral grains. However stonemasons use the term more broadly to encompass unmetamorphosed limestone.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It typically occurs in shiny streamlined forms asbestos fibers being the most notable exception. Marble is a rock resulting from metamorphism of sedimentary carbonate rocks most commonly limestone or dolomite rock. It is composed primarily of the mineral calcite caco 3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite.
