| 520 | |a Abstract Deeply buried Ordovician reservoirs within the central Tarim Basin, China, contain elevated concentrations of $ H_{2} $S. This study uses petrography, carbon and sulfur isotopes, and fluid inclusion microthermometry data to determine whether these elevated concentrations formed as a result of thermochemical sulfate reduction (TSR) and evaluates the influence of TSR on porosity. TSR-derived $ H_{2} $S is likely to have been incorporated into pyrite and minor sphalerite, as reflected by the similar $ δ^{34} $S values for $ H_{2} $S (15.0–23.4 ‰) and coarse crystalline pyrite (15–29.7 ‰). Sulfide precipitation caused an increase in acidity that allowed the dissolution of carbonates during TSR. The occurrence of dissolution during deep burial is indicated by: (1) the occurrence of dissolution pores within high-temperature (91.6–121 °C) burial calcite cement, (2) the coexistence of high-porosity sediments with elemental sulfur and pyrite in areas away from unconformities that would have undergone only limited interaction with meteoric water; (3) the presence of giant porous karst-filling calcites in association with coarse crystalline pyrite; and (4) a slightly negative shift in the $ δ^{13} $C values of some postbitumen calcite. Several factors probably limited the effect of TSR on the quality of reservoirs within the central Tarim Basin. The reactive $ SO_{4} $−2 involved in the TSR process was supplied by deep hydrothermal waters that contained dissolved sulfate rather than by the dissolution of anhydrite, meaning that only a limited increase in TSR-generated porosity occurred, restricted to areas along faults. The heterogeneity of metal ion concentrations within the reservoirs also constrained TSR-related carbonate dissolution, as after ferric ions within the reservoirs were consumed during advanced diagenesis, TSR-derived $ CO_{2} $ accumulated within the reservoirs, causing a negative shift in present-day $ CO_{2} $ $ δ^{13} $C values. | ||

This study uses petrography, carbon and sulfur isotopes, and fluid inclusion microthermometry data to determine whether these elevated concentrations formed as a result of thermochemical sulfate reduction (TSR) and evaluates the influence of TSR on porosity. TSR-derived $ H_{2} $S is likely to have been incorporated into pyrite and minor sphalerite, as reflected by the similar $ δ^{34} $S values for $ H_{2} $S (15.0–23.4 ‰) and coarse crystalline pyrite (15–29.7 ‰). Sulfide precipitation caused an increase in acidity that allowed the dissolution of carbonates during TSR. The occurrence of dissolution during deep burial is indicated by: (1) the occurrence of dissolution pores within high-temperature (91.6–121 °C) burial calcite cement, (2) the coexistence of high-porosity sediments with elemental sulfur and pyrite in areas away from unconformities that would have undergone only limited interaction with meteoric water; (3) the presence of giant porous karst-filling calcites in association with coarse crystalline pyrite; and (4) a slightly negative shift in the $ δ^{13} $C values of some postbitumen calcite. Several factors probably limited the effect of TSR on the quality of reservoirs within the central Tarim Basin. The reactive $ SO_{4} $−2 involved in the TSR process was supplied by deep hydrothermal waters that contained dissolved sulfate rather than by the dissolution of anhydrite, meaning that only a limited increase in TSR-generated porosity occurred, restricted to areas along faults.

This study uses petrography, carbon and sulfur isotopes, and fluid inclusion microthermometry data to determine whether these elevated concentrations formed as a result of thermochemical sulfate reduction (TSR) and evaluates the influence of TSR on porosity. TSR-derived $ H_{2} $S is likely to have been incorporated into pyrite and minor sphalerite, as reflected by the similar $ δ^{34} $S values for $ H_{2} $S (15.0–23.4 ‰) and coarse crystalline pyrite (15–29.7 ‰). Sulfide precipitation caused an increase in acidity that allowed the dissolution of carbonates during TSR. The occurrence of dissolution during deep burial is indicated by: (1) the occurrence of dissolution pores within high-temperature (91.6–121 °C) burial calcite cement, (2) the coexistence of high-porosity sediments with elemental sulfur and pyrite in areas away from unconformities that would have undergone only limited interaction with meteoric water; (3) the presence of giant porous karst-filling calcites in association with coarse crystalline pyrite; and (4) a slightly negative shift in the $ δ^{13} $C values of some postbitumen calcite. Several factors probably limited the effect of TSR on the quality of reservoirs within the central Tarim Basin. The reactive $ SO_{4} $−2 involved in the TSR process was supplied by deep hydrothermal waters that contained dissolved sulfate rather than by the dissolution of anhydrite, meaning that only a limited increase in TSR-generated porosity occurred, restricted to areas along faults. The heterogeneity of metal ion concentrations within the reservoirs also constrained TSR-related carbonate dissolution, as after ferric ions within the reservoirs were consumed during advanced diagenesis, TSR-derived $ CO_{2} $ accumulated within the reservoirs, causing a negative shift in present-day $ CO_{2} $ $ δ^{13} $C values.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Fluid inclusion</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Sulfur isotope</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">TSR</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Carbonate dissolution</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Tarim</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Cai, Chunfang</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Jia, Lianqi</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Gao, Yang</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Jiang, Zaixing</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wang, Tiankai</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Jiang, Lei</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Arabian journal of geosciences</subfield><subfield code="d">Berlin : Springer, 2008</subfield><subfield code="g">8(2014), 7 vom: 31.

The role of thermochemical sulfate reduction in the genesis of high-quality deep marine reservoirs within the central Tarim Basin, western China |
| abstract |
Abstract Deeply buried Ordovician reservoirs within the central Tarim Basin, China, contain elevated concentrations of $ H_{2} $S. This study uses petrography, carbon and sulfur isotopes, and fluid inclusion microthermometry data to determine whether these elevated concentrations formed as a result of thermochemical sulfate reduction (TSR) and evaluates the influence of TSR on porosity. TSR-derived $ H_{2} $S is likely to have been incorporated into pyrite and minor sphalerite, as reflected by the similar $ δ^{34} $S values for $ H_{2} $S (15.0–23.4 ‰) and coarse crystalline pyrite (15–29.7 ‰). Sulfide precipitation caused an increase in acidity that allowed the dissolution of carbonates during TSR. The occurrence of dissolution during deep burial is indicated by: (1) the occurrence of dissolution pores within high-temperature (91.6–121 °C) burial calcite cement, (2) the coexistence of high-porosity sediments with elemental sulfur and pyrite in areas away from unconformities that would have undergone only limited interaction with meteoric water; (3) the presence of giant porous karst-filling calcites in association with coarse crystalline pyrite; and (4) a slightly negative shift in the $ δ^{13} $C values of some postbitumen calcite. Several factors probably limited the effect of TSR on the quality of reservoirs within the central Tarim Basin. The reactive $ SO_{4} $−2 involved in the TSR process was supplied by deep hydrothermal waters that contained dissolved sulfate rather than by the dissolution of anhydrite, meaning that only a limited increase in TSR-generated porosity occurred, restricted to areas along faults. The heterogeneity of metal ion concentrations within the reservoirs also constrained TSR-related carbonate dissolution, as after ferric ions within the reservoirs were consumed during advanced diagenesis, TSR-derived $ CO_{2} $ accumulated within the reservoirs, causing a negative shift in present-day $ CO_{2} $ $ δ^{13} $C values. |
