Dolostoon
Dolostoon is a sedimentary carbonate rock in the dolomite family, characterized by a predominant dolomite (CaMg(CO3)2) composition with minor impurities of calcite, silica, and clay. It forms primarily through diagenetic dolomitization, in which magnesium-rich fluids alter limestone, replacing calcium with magnesium during burial or early diagenesis, often in warm, shallow-marine environments.
The texture is typically fine- to medium-grained, ranging from microcrystalline to interlocking dolomite grains. The rock
Distribution: Dolostoon is found in carbonate platforms and basins worldwide, often forming continuous units that can
Formation and diagenesis: Dolostoon forms when dolomitization proceeds to substantial depth, either through reflux of magnesium-rich
Economic and industrial relevance: It is used as crushed stone and aggregate in construction, and when sufficiently
