The most important geological processes that …When sedimentary rock contains a high concentration of dolomite – calcium magnesium carbonate CaMg(CO3)2 – we can call it dolomite, dolomite rock, or dolostone. The mineral dolomite is quite rare in …Such rocks form vast deposits; in Italy, the Alpine range known as the Dolomites is almost entirely composed of dolomite. However, unlike calcite, dolomite's sedimentary origin is enigmatic. Although it is the most stable carbonate mineral where magnesium is abundant in the marine environment, it is unknown as a primary mineral.Marble is a metamorphic rock consisting of carbonate minerals that recrystallize under the influence of heat, pressure, and aqueous solutions (most commonly calcite (CaCO 3) or dolomite (CaMg(CO 3) 2) and has a crystalline texture of varying thickness.

Dolostone (also referred to as dolomite) is the carbonate rock made of the mineral dolomite (CaMg(CO 3) 2). Dolostone is quite common (there’s a whole Italian mountain range named after it), which is surprising because marine organisms do not precipitate dolomite.The rock-forming process is known as dolomitization. Dolomite is a common rock, but the mineral dolomite is rarely found in sedimentary settings. Hence, most dolomites form when lime muds or mudstones are altered by post-depositional chemical change. These rocks also originate in the same sedimentary settings from where limestone comes.7. 4. 2021. ...

Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg (CO 3) 2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone.In sedimentary rock containing calcite and magnesium (Mg), diagenesis may transform the two minerals into dolomite (CaMg(CO 3) 2). Diagenesis may also reduce the pore space, or open volume, between sedimentary rock grains.Sedimentary Rock Specimens. Sedimentary rocks are formed at or near the surface of the earth.
