Marble Green Metamorphic Rock

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.

Marble green metamorphic rock. Geologists use the term marble to refer to metamorphosed limestone. 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. 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. Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite.

Marble is a rock resulting from metamorphism of sedimentary carbonate rocks most commonly limestone or dolomite rock. In geology marble is a metamorphic rock. However stonemasons use the term more broadly to encompass unmetamorphosed limestone. Serpentine is the green mineral in this rock known as serpentinite.

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. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Metamorphism causes variable recrystallization of the original carbonate mineral grains. Green marble green marble.

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. The resulting marble rock is typically composed of an interlocking mosaic of carbonate crystals.
