Limited dolomitization of the calcite around the edges of the fossils and in the matrix of the concretion occurred at a later stage. |
Dolomites are rarely fossiliferous, as the process of dolomitization tends to destroy any organic remains originally present. |
Examples of dolomitization may be obtained in practically every geological formation in which limestones occur. |
It contains ellipsoidal primordial facies, complete dolomitization and vuggy porosity of touching-vug type. |
Burial dolomitization of the Middle Ordovician Glenwood Formation by evaporitic brines. |
The only volumetrically important and widespread diagenetic effect of groundwater flow on carbonates in near-surface evaporitic settings is reflux dolomitization. |
