At 600~ serpentine begins todecompose. According to [I] the structure of serpentine breaks down at 620-800~ The products then form new phases - forsterite (crystalline) and magnesium metasilicate (x-ray morphous). At 800~ dolomite breaks down in to free magnesium oxide and calcium carbonate. Dissociation of CaCO 3 occurs at 800-I000~ to …

Dolomite supplies CaO and MgO. Dolomite is calcium magnesium carbonate, theoretical formula CaMg (CO3)2. Pure dolomite, with exactly equal numbers of calcium and magnesium atoms, is formed by precipitation out of waters in which both are dissolved. Most dolomite, however, is formed when magnesium-rich waters seep through calcium …

Iranian dolomite (CaMg(CO 3) 2) which consists of double-layered carbonates with Ca 2+ and Mg 2+ ions was utilized as a heterogeneous base catalyst in the C C, C N, and C S bond forming reactions via the Henry, Knoevenagel, aza-Michael, and thia-Michael transformations under mild conditions in water. Iranian dolomite has been characterized …
Sedimentary rock - Limestones, Dolomites, Calcite: 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 …
Dolomite (/ˈdɒl.əˌmaɪt, ˈdoʊ.lə-/) is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally CaMg(CO3)2. The term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite. An alternative name sometimes used for the dolomitic rock type is dolostone.

Dolomite is the carbonate mineral CaMg(CO3)2,often with small amounts of iron, manganese,or excess calcium, which replace some of themagnesium; cobalt, zinc, lead, and barium aremore rarely found. Dolomite is a very common mineral, occurringin a variety of geologic settings. It is oftenfound in ultrabasic igneous rocks, notably incarbonates and ...
Since dolomite is a mixture of calcium carbonate and magnesium carbonate (MgCO3), we need to convert the mass of CaCO3 to the mass of dolomite by using the ratio of the molecular weights of CaCO3 and CaMg(CO3)2: 100.09 g CaCO3 / (2 × 84.31 g CaMg(CO3)2) = 0.595. So the mass of dolomite in the soil sample is: 1.16 g CaCO3 / …
