Marble Original Rock

Petrographically marbles are massive rather than thin layered and consist of a.

Marble original 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 under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is. The marble rocks is an area along the narmada river in central india near the city of jabalpur. Marble is a metamorphic rock resulting from regional or at times contact metamorphism of sedimentary carbonate rocks either limestone or dolostone. In its pure form marble is a white stone with a crystalline and sugary appearance consisting of calcium carbonate caco 3 usually marble contains other minerals including quartz graphite pyrite and iron oxides these minerals can give marble a pink brown gray green or variegated coloration.

Marble granular limestone or dolomite i e rock composed of calcium magnesium carbonate that has been recrystallized under the influence of heat pressure and aqueous solutions. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Marble is a rock resulting from metamorphism of sedimentary carbonate rocks most commonly limestone or dolomite rock. The resulting marble rock is typically composed of an interlocking mosaic of carbonate crystals.

Metamorphism causes variable recrystallization of the original carbonate mineral grains. This metamorphic process causes a complete recrystallization of the original rock into an interlocking mosaic of calcite and or dolomite crystals.
