Towards understanding the origin of massive

1. Introduction. Dolomite, one of the most enigmatic minerals, is abundant in pre-Cenozoic strata but rare in Cenozoic and modern sediments. It is hypothesized that such sharp contrast of dolomite distribution might be linked to the changes of environmental conditions, although factors controlling dolomite precipitation in the global scale remains elusive (Burns et al., 2000).
