Marble Green Metamorphic Rock

Serpentine is the green mineral in this rock known as serpentinite.

Marble green metamorphic 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. Marble may be foliated. Metamorphism causes variable recrystallization of the original carbonate mineral grains. Geologists use the term marble to refer to metamorphosed limestone.

Green marble green marble. J brew flickr cc by sa 2 0 serpentine is a metamorphic mineral that occurs in some marbles but is more often found by itself in serpentinite. However stonemasons use the term more broadly to encompass unmetamorphosed limestone. Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite.

Before knowing anything about green marble we must be accustomed to marble as a basic and geological term. The resulting marble rock is typically composed of an interlocking mosaic of carbonate crystals. Marble marble is a granular metamorphic rock it is derived from limestone or dolomite and it consists of a mass of interlocking grains of calcite or the mineral dolomite. It typically occurs in shiny streamlined forms asbestos fibers being the most notable exception.

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. Marble is a rock resulting from metamorphism of sedimentary carbonate rocks most commonly limestone or dolomite rock.
