“…Negative values of carbon isotopes could have resulted from organic matter alteration during penetration of meteoric water. The Lower Cretaceous unconformity could have also allowed meteoric water recharges in the Lower and Upper Jurassic formations and increased the effect of meteoric water on these deposits (e.g., Vincent et al 2007). …”

“…4F, G). Evidence includes closer packing, increasing suture and concave-convex contacts, fracturing ooid and some shells such as brachiopods, bryozoans and echinoderms, pressure dissolution at grain contacts and the formation of stylolites (e.g., Vincent et al 2007).…”

“…Early cementation and pervasive dolomitization tend to retard the onset and efficiency of chemical compaction. Marine and meteoric processes mostly occur in early stages, and shallow burial but physical and especially chemical compaction, fracturing and blocky cementation occur in late stages and deeper part of burial (e.g., Vincent et al 2007). Dolomitization and neomorphism occur in different depths of burial.…”

The Upper Jurassic Mozduran Formation with a thickness of 420 m at the type locality is the most important gas-bearing reservoir in NE Iran. It is mainly composed of limestone, dolostone with shale and gypsum interbeds that grade into coarser siliciclastics in the easternmost part of the basin. Eight stratigraphic sections were studied in detail in south of the Agh-Darband area. These analyses suggest that four carbonate facies associations and three siliciclastic lithofacies were deposited in shallow marine to shoreline environments, respectively. Cementation, compaction, dissolution, micritization, neomorphism, hematitization, dolomitization and fracturing are diagenetic processes that affected these sediments. Stable isotope variations of d 18 O and d 13 C in carbonate rocks show two different trends. High depletion of d 18 O and low variation of d 13 C probably reflect increasing temperatures during burial diagenesis, while the higher depletion in carbon isotope values with low variations in oxygen isotopes are related to fresh water flushing during meteoric diagenesis. Negative values of carbon isotopes may have also resulted from organic matter alteration during penetration of meteoric water. Fe and Mn enrichment with depletion of d 18 O also supports the contention that alteration associated with higher depletion in carbon isotope values with low variations in oxygen isotopes took place during meteoric diagenesis. The presence of bright luminescence indicates redox conditions during precipitation of calcite cement.

“…In situ Secondary Ion Mass Spectrometry (SIMS) has provided a powerful technique for studying basin fluid activities [25][26][27][28][29][30]. SIMS can solve the traditional test difficulties; for example, a small number of samples cannot meet the test 2 Geofluids requirements or the analysis results are often the average value of multiphase fluid mixing.…”

Multiphase Calcite Cementation and Fluids Evolution of a Deeply Buried Carbonate Reservoir in the Upper Ordovician Lianglitag Formation, Tahe Oilfield, Tarim Basin, NW China

Oil and gas have been found in the Upper Ordovician Lianglitag Formation carbonates in the Tahe Oilfield, Tarim Basin, NW China. This study documents the origin of diagenetic fluids by using a combination of petrology, SIMS, fluid inclusion, and radiogenic isotope analysis. Six stages of calcite cements were revealed. C1-C2 formed in marine to early burial environments. C3 has relatively low 18 O VPDB values (−8.45‰ to −6.50‰) and likely has a meteoric origin. Meteoric water probably fluxed into aquifers during the Early Paleozoic and Late Paleozoic uplift. C4 has 18 O VPDB values typically 3‰ higher than those of C3, and probably formed during shallow burial. C5 displays relatively negative 18 O VPDB values (−8.26‰ to −5.12‰), and the moderate-tohigh fluid-inclusion temperatures imply that it precipitated in burial environments. C6 shows homogenization temperatures (up to 200 ∘ C) higher than the maximum burial and much lower salinities (<10.61 wt% NaCl), which may suggest that the fluid was deeply recycled meteoric water. The average 87 Sr/ 86 Sr ratios of fracture-and vug-filling calcite cements are much higher, indicative of incorporation of radiogenic Sr. Caves and fractures constitute the dominant reservoir spaces. A corresponding diagenesis-related reservoir evolution model was established that favors exploration and prediction.
