Marble sandatlas.org

Marble is a metamorphic rock consisting predominantly of calcite or dolomite. It is a metamorphosed carbonate rock (limestone or dolomite rock). Marble is a sparkling and typically granoblastic rock. Granoblastic rocks have uniformly sized, equidimensional, anhedral grains produced by recrystallization in a solid state (metamorphism).

Sedimentary rock Limestones and dolomites Britannica.com

Sedimentary rock Limestones and dolomites: Limestones and dolomites are collectively referred to as carbonates because they consist predominantly of the carbonate minerals calcite (CaCO3) and dolomite (CaMg[CO3]2). Almost all dolomites are believed to be produced by recrystallization of preexisting limestones, although the exact details of this dolomitization process continue to be debated.

Limestones which are composed mostly of calcite (CaCO 3) or high Mg calcite [(Ca,Mg)CO 3], and . Dolostones which are composed mostly of dolomite [CaMg(CO 3) 2].
