dolomite marble and calcite marble building blocks stability

Marble According to ASTM, commercial marble includes all crystalline rocks composed predominantly of calcite, dolomite, or serpentine and ca- pable of taking a high polish. Geologically, marble is considered only as a metamorphic rock foxed by the recrystallization of a limestone or dolomite under relatively high heat and pressure.

Limestone

Description. Limestone (See also Marble and Dolomite) Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate. Limestone varies in colour from cream through whiote to medium dark grey (when freshly broken).

 · Dolomite formation is a mineral replacement reaction that affects extensive rock volumes and comprises a large fraction of oil and gas reservoirs [1,2]. The most accepted hypothesis is the ''dolomitization'' of limestone by Mg-rich fluids [3]. The objective of this research is to study the replacement mechanism of calcite by dolomite, the role of grain boundaries, highlighted by …

Calcite vs. Limestone

 · A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO3)2. In fact, in old USGS publications, dolomite was referred to as magnesian limestone, a term now reserved for magnesium-deficient dolomites or magnesium-rich limestones. About 10% of sedimentary rocks are limestones.

 · Formation of dolomite can occur via two possible mechanisms – i) direct precipitation from solution to form primary dolomite, and ii) dolomitization process in which calcite undergoes dissolution supplying the Ca 2+ ions followed by the precipitation of dolomite from a solution rich in Mg 2+ ions [1,2]. Therefore, it is not uncommon to ...

Dolomite is marble, it just has magnesium in it. The term "marble" came from stone masons when a limestone, which is calcium carbonate, polished up to a shine; it was called marble. Marble is metamorphosed limestone. All limestones including dolomite will disappear in muriatic acid (I''ve done it) because they are calcium carbonate.
