Le marbre peut également se former par le métamorphisme d'autres types de roches, comme le calcaire ou la dolomite.Marbre Propriétés, utilisations, formation

The effect of dolomite amendment on soil organic carbon

2021年1月7日 The size of lime material is vital for the efficiency of ameliorating soil acidity, thereby influencing soil biochemical processes. However, the effects of different sized lime material application on soil organic carbon (SOC) mineralization are yet to be elucidated. Therefore, a 35-day incubation experiment was conducted to determine the effects of 2016年12月2日 The offset of slopes between the variable and the constant AFFs increases depending on the decreasing temperature. For example, If the Δ47 value of dolomite is 0.75‰, the Δ47-temperature (16 °C) corrected by variable AFF is nearly four times higher than the result (4.8 °C) corrected by constant AFFs when using the equation of Calibration of dolomite clumped isotope thermometry2011年6月1日 A calibration for synthetic dolomite precipitated at temperatures of 25–350 °C has been presented only in abstract form (Bonifacie et al., 2011) but appears consistent with the calcite data ...Calibration and applications of the dolomite clumped

Dolomite loses upto 50% mass on ignition and the residue ...The dolomite of most dolostones is granular, with the individual grains ranging in size from microscopic up to a few millimetres across. Most dolomite marbles are coarsely granular with individual grains ranging between 2 and 6 millimetres (0.079 and 0.24 inch) in greatest dimension. Vein dolomite grains may be up to several centimetres across.Dolomite Formation, Structure, Properties, Uses, Facts2018年1月1日 Stoichiometric, ordered dolomite readily forms at temperatures above 100 °C (Arvidson and Mackenzie 1999); however, changes in temperature and solution chemistry significantly influence the stoichiometry of precipitated phases.Thermodynamic constants and isotopic fractionation factors have been developed for dolomite at high Dolomite and Dolomitization SpringerLink

Influence of ameliorating soil acidity with dolomite on the

2017年2月21日 Lime or dolomite is commonly implemented to ameliorate soil acidity. However, the impact of dolomite on CO2 emissions from acidic soils is largely unknown.
