The results showed that the so-called "dolomite phenomenon" is widely represented and is clearly manifested in the appearance of a peculiar flora, very rich in endemisms, on dry soils, poor in nutrients, and with a high Mg level. Although dolomite habitats cause

The influence of Ca–Mg disorder on the growth of …

These data allowed us to propose a new growth model for primary dolomite, which hypothesizes that dolomite forms from a Ca 2+ –Mg 2+-rich fluid by initially nucleating small calcite crystals, which act as substrates for successive dolomite formation.

Dolomite and dolomitization model

 · Burial dolomitization involves prime mechanism which is the dewatering of basinal mud rocks due to compaction and removal of Mg-rich fluids into neighboring shelf edge. Expulsion of water and changes of clay minerals with enlarged burial and increasing temperature suggest that it would liberate Mg ions along with Fe ion.

Dolomite: a low cost thermochemical energy storage …

The commercial dolomite samples begin decomposition at higher temperatures (Rich-A: 550 C, Wath-A: 800 C) than the synthetic dolomite (Synth-C-cat: 500 C), which also decomposes more gradually. Interestingly, both larnite (Ca 2 SiO 4 ) and Ca 3 Al 2 O 6 are not observed at these temperatures, in contrast to their large crystalline fraction after heat treatment at 1000 °C (in Rich-B and Wath-B).

Mg-rich dolomite (d 104 =2.904 A) have supper lattice domains with ~5 nm in size, whereas high Mg calcite (d 104 =2.933 A) have supper lattice domains with ~3nm in size. A relationship between value and chemical composition is established for the prododolomite.

DOLOMITE (Calcium Magnesium Carbonate)

Magnesium rich ground waters that have a significant amount of salinity are probably crucial and warm, tropical near ocean environments are probably the best source of dolomite formation. Dolomite in addition to the sedimentary beds is also found in metamorphic marbles, hydrothermal veins and replacement deposits.

Properties of Ca-Rich and Mg-Rich Carbonate Films on …

The Ca-rich film also exhibited a slightly higher adhesion than did the dolomite substrate; however, the critical shear stresses for the two tip−surface contacts were indistinguishable. A comparative study with a Mg-rich film did not yield noticeable force modulation contrast, indicating similar surface stiffness of the film and the dolomite surface.

Enthalpies of formation of dolomite and of magnesian calcites

pressure), dolomite undergoes a cation-disordering reac-tion (Goldsmith and Heard, 196l; Reeder and Wenk, 1983) to a calcitelike phase. Mg-rich calcites occur in low-temperature environments and are of both inorganic and biogenic origin. The biogenic

Surface chemistry allows for abiotic precipitation of …

 · Mg-rich phases nucleate exclusively on carboxylated polystyrene spheres along with calcite, whereas aragonite forms in solution via homogeneous nucleation. We infer that Mg ions are complexed and dewatered by surface-bound carboxyl groups, thus decreasing the energy required for carbonation.

7 Sedimentary Minerals and Sedimentary Rocks – Mineralogy

For example, most dolomite is secondary and forms by reaction of calcite with Mg-rich water during diagenesis. Magnesite, (MgCO 3), a related carbonate, forms as an alteration product of mafic and ultramafic rocks. Hydromagnesite (a hydrated equivalent of
