Quartzite vs Marble | Precision Stoneworks

Marble is comprised of recrystallized carbonate minerals such as calcite or dolomite. The sedimentary carbonate rocks are converted into marble by heat and pressure. The subsequent marble rock is comprised of an interconnecting mixture of carbonate crystals, which have an altered texture and structure than the initial carbonate rock.

Sedimentary rock - Carbonate rocks: limestones and dolomites: Limestones and dolostones (dolomites) make up the bulk of the nonterrigenous sedimentary rocks. Limestones are for the most part primary carbonate rocks. They consist of 50 percent or more calcite and aragonite (both CaCO3). Dolomites are mainly produced by the secondary alteration or replacement of limestones; i.e., the …

Calcite as Limestone and Marble. Limestone is a sedimentary rock that is composed primarily of calcite. It forms from both the chemical precipitation of calcium carbonate and the transformation of shell, coral, fecal and algal debris into calcite during diagenesis.

Calcite - Wikipedia

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO 3). The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as "calcite". Other polymorphs of calcium carbonate are the minerals aragonite and vaterite.

Limestone - Wikipedia

Limestone is a sedimentary rock, composed mainly of skeletal fragments of marine organisms such as coral, forams and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).. About 10% of sedimentary rocks are limestones. The solubility of limestone in water and weak acid solutions leads to karst landscapes, in which ...
