Abstract

Studies of fluid inclusions in regionally extensive late dolomite cement (LDC) throughout the Ozark region show that CO2 effervescence was widespread during dolomite precipitation. LDC with trace amounts of sulfides can be deposited by effervescences of a CO2-saturated basin brine as it migrates to shallower levels and lower conifning pressures. This precipitation mechanism best explains occurrences of LDC in the Ozark region and may account for LDC in the Ozark region and may account for LDC found in sedimentary basins worldwide. -from Authors
