“…The higher in the lower section (table 2) also support the production capability of gas and oil (McCarthy et al 2011). Earlier study pursued on black shales collected from subsurface mining zones of the Matanomadh area also show similar results with association of type II/III and samples of surface area having type III/IV kerogen (Mishra et al 2014). The study of Dutta et al (2011) shows shale samples in the Matanomadh mine to have type IV kerogen.…”

“…Characterization of black shales from the northern and southern onland part of this basin were previously done from the Jhuran Formation in and around Khari River channel, Rudramata bridge, and Zara, Dharang and Jhumara, Palara and Ler villages (Arora et al 2015(Arora et al , 2017. Similar studies have been carried on the black shales of the Naredi Formation from the Panandhro, Umarsar and Matanomadh lignite mines in this basin (Dutta et al 2011;Sahay 2011;Mishra et al 2014). In addition, it is important to note that sediments from upper Jurassic as well as Late Cretaceous to Eocene times contributed 25 and 2.8% of global hydrocarbons (oil and gas), respectively (Klemme and Ulmishek 1991).…”

“…The S 1 (thermo-vaporized free hydrocarbons) and S 2 (hydrocarbons from cracking of organic matters) values are low (up to 0.02 and 0.15 mg HC/g rock) in these samples. The hydrogen index (HI) and oxygen index (OI) were calculated for each samples using the formula HI = (100×S 2 )/TOC and OI = (100×S 3 )/TOC, respectively (Lafargue et al 1988;McCarthy et al 2011;Mishra et al 2014). The HI and OI lie between 8-28 mg HC/g TOC and 105−286 mg CO 2 /g TOC, respectively.…”

“…Excellent positive correlation between S 1 and S 2 is also observed in both the sites (R = 0.99 for NNSR and R = 0.93 in core). Mishra et al (2014) suggested good positive correlation between S 1 and S 2 could be an indicator of common source of organic matter as well as absence of contamination. Hence, we consider that higher organic carbon in both the areas might have been derived from a common source and the samples have witnessed negligible to minimal surficial contamination.…”

“…Black shales have been reported from several sedimentary basins of India, which include the Paleoproterozoic Cuddapah basin (Manikyamba et al 2008), Mesoproterozoic to Neoproterozoic Vindhyan basin (Banerjee et al 2006;Paikaray et al 2008;Bhaskar 2013), Permian Gondwana basin of the Krishna-Godavari valley (Rao 2001; Bhaskar 2013), Permian to Mesozoic Gondwana basins of the Damodar Valley (Bhaskar 2013;Bourah and Ganapathi 2015;Mani et al 2015;Tewari et al 2016), Permian-Triassic basins in the Himalayan Region (Mani et al 2014), Paleogene Cambay basin (Banerjee and Rao 1993;Bhaskar 2013), Paleogene of the Cauvery basin (Chandra et al 1991;Bhaskar 2013) and the Mesozoic-Paleogene rocks of the Kachchh basin (Dutta et al 2011;Sahay 2011;Mishra et al 2014;Arora et al 2015Arora et al , 2017. Thick and well-developed organic-rich black shales constitute distinct stratigraphic units of the onland Kachchh basin of western India (figure 1).…”

Thirty-three black shale samples from four locations on the onland Kachchh basin, western India were analyzed to characterize organic carbon (OC), thermal maturity and to determine the hydrocarbon potential of the basin. Upper Jurassic black shales from the Jhuran Formation (Dhonsa and Kodki areas) are characterized by the presence of chlorite, halloysite, high T max , low OC, low hydrogen index and high oxygen index. These parameters indicate the OC as type IV kerogen, formed in a marine environment. The rocks attained thermal maturity possibly during Deccan volcanism. Early Eocene samples of the Naredi Formation (Naliya-Narayan Sarovar Road (NNSR) and the Matanomadh areas) are rich in TOC, smectite, chlorite and framboidal pyrite, but have low T max. These indicate deposition of sediments in a reducing condition, probably in a lagoonal/marsh/swamp environment. Organic carbon of the Naredi Formation of NNSR may be considered as immature type III to IV kerogen, prone to generate coal. Core samples from the Naredi Formation of the Matanomadh area show two fold distribution in terms of kerogen. Organic carbon of the upper section is immature type III to IV kerogen, but the lower section has type II to III kerogen having potential to generate oil and gas after attaining appropriate thermal maturity.

A well‐developed 86 m‐thick Cenozoic sedimentary succession in the Matanomadh area, western Kachchh, was studied to assess the stratigraphic positions of different units, ascertain depositional environments, and the degree of climatic controls over time depositional processes. Age‐diagnostic nannoplankton species Cyclicargolithus floridanus (46.29–12.1 Ma), Reticulofenestra dictyoda (53–30.8 Ma), Reticulofenestra minuta (50.5–2.59 Ma) and foraminiferal species, for example, Orbulinoides beckmanni (41–39.5 Ma) found across studied units envisage the stratigraphic age and palaeoenvironment. CaO with strong negative elemental correlation, binary/ternary discriminant tectonic and depositional regimes cross‐plot from units indicate the biogenic origin of limestones and shales were formed in typical passive, marginal, shallow littoral settings with plausible detritus influx from Deccan basaltic provenance. Total organic carbon with TE‐REE respectively connotes a sedimentation process in a nearly consistent open shallow marine, locally transient semi‐restricted marginal basin in a tropical‐equatorial region. Furthermore, principal component analysis (PCA) of weathering indices based on elemental abundance and X‐ray diffraction data of clays deterministically suggest with empirical relation between humid tropical climate‐induced weathering and fluctuant terrestrial influx. Palaeoredox indices with biological data demonstrate localized redox‐stratified conditions. However, coherent signatures of the global events such as Eocene Thermal Maximum‐2, Middle Eocene Climatic Optimum, and Mid Miocene Climatic Optimum can be traced and validated by synthesizing geochemical data for direct/indirect estimation of sediment routing, rainfall (αAlMg and αAlCa) and climate proxies (PCA), productivity indices (Babio, Cubio and Nibio), and localized periodic oxic‐dysoxic environment (V/Cr, U/Th, Ni/Co) from core samples.
