Petrographically marbles are massive rather than thin layered and consist of a.
Marble original rock.
Marble is a metamorphic rock resulting from regional or at times contact metamorphism of sedimentary carbonate rocks either limestone or dolostone.
Commercially it includes all decorative calcium rich rocks that can be polished as well as certain serpentines verd antiques.
The resulting marble rock is typically composed of an interlocking mosaic of carbonate crystals.
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.
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.
Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.
Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat.
Marble is a rock resulting from metamorphism of sedimentary carbonate rocks most commonly limestone or dolomite rock.
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.
