“…Palynological studies from boreholes and well cuttings (Lawal andMoullade, 1986 andAbubakar et al, 2011) suggest a Cenomanian age for the Yolde Formation. The Yolde Formation has been recently interpreted as shoreface to offshore marine, indicating shallow 30 marine conditions (Sarki Yandoka et al, 2015). The palynomorph recovery of the samples of the upper Bima and Yolde formations for this present study is poor.…”

“…The formation forms lowlying outcrops and is exposed in the Gongola and Yola sub-basins with its type locality being in Yolde village. The formation was initially interpreted as a fluvial to marine deposit (Zaborski et al, 1997), and subsequent work interpreted it as a coastal deposit (Sarki Yandoka et al, 2015). The formation was considered late Cenomanian in age based on occurrences of Classopollis brasiliensis and Triorites africaensis (Lawal and Moullade, 1986).…”

“…All the T max analyses show that the siliceous shale of Niutitang Formation and Longmaxi Formation has reached maturity. T S /(Tm + Ts) ratio increases with the rising maturity and stays around 0.5 in the late hydrocarbon generation peroid [42,48]. The ratios of both Niutitang Formation and Longmaxi Formation samples are all 0.49 (Table 5), futher implying that the shales of Niutitang Formation and Longmaxi Formation have entered maturity.…”

“…The distribution pattern of tricyclic terpane C 21 , C 23 and C 24 can illustrate organic matter input, to some extent [46,48]. Researchers found that the "V" shape of C 21 , C 23 , and C 24 in tricyclic terpane is usually associated with a salt-water environment and can reflect lower biological input of bacteria and algae [36].…”

Measurements of total organic carbon, Rock-Eval pyrolysis, X-ray diffraction, scanning electron microscope, maceral examination, gas chromatography, and gas chromatography-mass spectrometry were conducted on the organic-rich shale of Lower Paleozoic Niutitang Formation and Longmaxi Formation in Dabashan foreland belt to discuss the organic matter characteristic, organic matter origin, redox condition, and salinity. The results indicate that the Niutiang Formation and Longmaxi Formation organic-rich shale are good and very good source rocks with Type I kerogen. Both of the shales have reached mature stage for generating gas. Biomarker analyses indicate that the organic matter origin of Niutitang Formation and Longmaxi Formation organic-rich shale are all derived from the lower bacteria and algae, and the organic matter are all suffered different biodegradation degrees. During Niutitang Formation and Longmaxi Formation period, the redox conditions are both anoxic with no stratification and the sedimentary water is normal marine water.

“…Powder XRD analyses of the bulk samples were conducted on a Siemens D5000 X‐ray diffractometer. The minerals were identified from the diffractograms by referencing to the ICDD Powder Diffraction File (Srodon et al, ; Yandoka et al, ). The initial mineral compositions (quartz, feldspar, carbonate, and clay minerals) of the Xu‐4 sandstones were determined using a semiquantitative XRD analyses.…”

Mineralogical, petrographic, and geochemical analyses were performed to investigate the sandstone composition and texture, pore system, and diagenetic minerals of Upper Triassic sandstones in the Central Sichuan Basin, Southwest China. The results show that authigenic quartz, clay minerals, and carbonates are the main pore‐filling constituents. The pore systems consist of intergranular porosity, secondary porosity, microporosity, and microfractures. Loss of depositional porosity is greater due to compaction than to cementation. Eodiagenesis includes mechanical compaction, precipitation of early calcite cements, kaolinite, and smectite, and leaching of feldspars by meteoric water. Mesodiagenesis consists of compaction, framework grain dissolution, and subsequent precipitation of illite, quartz, and late carbonate cements. Six lithofacies were identified on the basis of petrographic analyses, namely, (a) argillaceous sandstones; (b) poorly sorted sandstones; (c) quartz‐cemented sandstones; (d) carbonate‐cemented sandstones; (e) clay‐mineral‐cemented sandstones, and (f) clean sandstones with abundant secondary porosity. The best reservoir‐quality rocks have high percentages of detrital quartz but low percentages of matrix, quartz, and carbonate cement. Differences in textural and compositional attributes of various lithofacies significantly affect porosity‐depth trends. The diagenetic evolution pathways and reservoir‐quality prediction models of various lithofacies are reconstructed by integrated petrographic data. This work provides insights into describing the different lithofacies by petrographic analysis and helps to investigate how detrital composition and texture influence the diagenesis and reservoir quality evolution in tight gas sandstones.
