The original mineral name dolomie was given by N.T. Saussare, in 1792, in honor of the French geologist Deodat Guy de Dolomieu (1750–1801) and was first applied to rocks in the Tyrolean Alps (Bourrouilh-Le Jan, 2000).Dolomite, the rock, contains a large proportion of dolomite the mineral. Ideal dolomite has a crystal lattice consisting of …
Dolomite is the most important component of the prolific reservoirs in the Ma55 to Ma51 submembers of the Ordovician Majiagou Formation in the central Yishan Slope, Ordos Basin. However, the origins of the different types of dolomite are unclear because of the different diagenetic environments and complex diagenetic fluids. This …
Several literature interpretations discovered the potential of dolomite waste powder as a cement replacement in concrete [72, 85, 86].Balakrishnan and Paulose [] investigated the consequence of the self-compacting concrete (SCC) with dolomite powder (DP) as a partial substitute for cement and fly ash (FA).The maximum compressive …

La dolomia è una roccia sedimentaria carbonatica costituita principalmente dal minerale dolomite, chimicamente un carbonato doppio di calcio e magnesio. Questa roccia prende il suo nome (come il minerale dolomite) dal naturalista e geologo francese Déodat de Dolomieu (1750-1801), il quale nel 1791 osservò tale roccia nei gruppi …
Dolomite is a relatively inexpensive mineral, and it is widely available around the world. It is not considered valuable from a monetary standpoint, Is Dolomite Rare? Dolomite is not a rare mineral, and it can be found in sedimentary basins all over the world. However, high-quality dolomite that is free of impurities is somewhat rare.

Dolomite increases the production of H2 and CO and decreases the production of CH4, CO2, and CnHm. Olivine has a slight effect on gas compositions. Dolomite is catalytically more active than olivine. Dolomite is 1.4 times more effective than olivine for in-bed applications. Dolomite generates 4–6 times more particulates than olivine.
