Origin of late dolomite cement by CO2-saturated deep basin brines: evidence from the Ozark region, central United States Origin of late dolomite cement by CO2-saturated deep basin brines: evidence from the Ozark region, central United States
Studies of fluid inclusions in regionally extensive late dolomite cement (LDC) throughout the Ozark region show that CO2 effervescence was widespread during dolomite precipitation. On the basis of quantitative analyses of inclusion fluids, reaction-path modeling shows that LDC with trace amounts of sulfides can be deposited by effervescence of a CO2-saturated basin brine as it migrates...

Characterization of carbon in sediment-hosted disseminated gold deposits, north central Nevada Characterization of carbon in sediment-hosted disseminated gold deposits, north central Nevada
The gray, dark gray and black colors of the sediments and the presence of pyrite in the Carlin, Jerritt Canyon, Horse Canyon, Betze, and Gold Acres sediment-hosted disseminated gold (SHDG) deposits indicate that these rocks are not oxidized with respect to carbon and iron sulfide. The organic matter in the host rocks of SHDG deposits in north-central Nevada is cryptocrystalline graphite...
