Clumped isotopes geothermometry was applied to two dolomitic hydrocarbon reservoirs. Results indicate that late burial dolomitization occurred at ~110°C in the Albian Pinda dolostone (offshore Angola) and ~90°C in the Mano-Meillon dolostone (Aquitaine Basin, France), and did not continue on during subsequent burial/thermal evolution to present-day conditions (150160°C). This study illustrates t...

Based on an integrated geochemical characterized by extremely high Sr and petrographic investigation of dolomites concentrations, which reflect high from two cores drilled on Great Bahama concentrations of Sr in the pore fluids. Bank, we have determined three different The high concentrations of Sr in the pore mechanisms of formation for the dolomites fluids arise through the continued which ar...

Abstract This study evaluates examples of hydrothermal dolomitization in the Middle Cambrian Cathedral Formation Western Canadian Sedimentary Basin. Kilometer-scale dolomite bodies within carbonate platform are composed replacement (RD), with saddle dolomite-cemented (SDC) breccias occurring along faults. These overlain by Stephen (Burgess Shale equivalent) shale. RD is crosscut low-amplitude s...

the berriasian-valanginian fahliyan formation forms one of the giant reservoirs in the subsurface of the abadan plain, onshore iran. a detailed petrographical analysis of the available cores and thin sections revealed that the different diagenetic parameters influenced the reservoir quality of the fahliyan formation in this field. the fahliyan formation has been influenced by three diagenetic e...
