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 green metamorphic rock. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. However stonemasons use the term more broadly to encompass unmetamorphosed limestone. Marble is a rock resulting from metamorphism of sedimentary carbonate rocks most commonly limestone or dolomite rock. 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.

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. Serpentine is the green mineral in this rock known as serpentinite. Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite. Green marble green marble.

Metamorphism causes variable recrystallization of the original carbonate mineral grains. Marble may be foliated. 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.

Geologists use the term marble to refer to metamorphosed limestone. When metamorphism of sedimentary carbonate rocks takes place in the crust of earth due to contact of hot magma the calcite rocks such as limestone or dolomites are turned into marble.
