Among various geochemical and petrographic approaches, dolomite crystal morphology and dolostone fabric have been widely applied in the study of ancient dolostones. It is proposed that dolomite crystal morphologies and the rock fabric may reflect the formation temperature, and thus can be used to distinguish different generations of dolomite.

A route for the direct crystallization of dolomite

Thus, we hypothesize that an amorphous precursor is a necessary prerequisite for the crystallization of proto-dolomite/dolomite and that the spherulitic crystal growth mechanism observed in the pure CaCO 3 system also controls the "direct" formation of proto-dolomite and dolomite in the Mg-Ca-CO 3 system. To address this we characterized ...
