Sands belonging to Kamalapuram Formation of Paleocene‐Eocene age are deposited in Cauvery basin as incised valley fill during a regressive cycle. Here we attempt to quantify the influence of diagenesis on pore‐filling materials using rock physics template constrained by geohistory modelling. Primarily, porosity–velocity and acoustic impedance – the ratio of P‐wave and S‐wave velocity (VP/Vs) cross‐plots are used as rock physics templates. Rock physics template has efficiently quantified pore‐filling materials namely; contact cement and non‐contact cement. The estimated contact cement and non‐contact cement are correlated with conventional petrophysical logs within the selected depth interval. Further, this correlation is used to interpret the composition of pore‐filling materials. Shallower depth intervals (I and II) exhibit moderate non‐contact cement (4–5%) and insignificant contact cement (1–2% approx.) depositions. However, deeper interval (III) records a significant amount of pore‐filling materials amounting average of 12% non‐contact cement and 4% contact cement. Pore‐filling materials demonstrate a positive correlation with the depth of burial. The fluid response is substantially affected by the degree of diagenesis, composition and spatial distribution of pore‐filling materials. Shallower depth intervals (1770–1786 m and 1858–1878 m) are relatively more sensitive to fluid changes as it is affected by insignificant contact cement. The depth interval 1770–1786 m shows class II (oil) and class III (gas) amplitude variation with offset anomalies. The sand occurring in depth interval 1858–1878 m demonstrates class IIP (oil) and II (gas) anomaly. The deeper interval (2118–2170 m) is comparatively stiffer and demonstrates class I amplitude variation with offset (oil and gas sand) anomaly.

“…The age of the Karai Shale, marking a major transgressive cycle ranges from Early Albian to Middle Turonian (Gowtham et al, 2019). The Albian age, indicated by index fossil taxa, as well as new Ar/Ar dating of glauconite significantly improves the calibration of OAE 1d in the Cauvery Basin (Nagendra and Reddy, 2017;Bansal et al, 2019a).The transition from the shallow shelf-originated Dalmiapuram Formation to the deeper shelf-originated Karai Shale Formation records a transgressive trend (Sarkar et al, 2014).…”

This review presents a brief appraisal of the present understanding regarding marine and fluvial sedimentation in peninsular India in the background of global tectono-thermal events and relative sea level changes during the Phanerozoic. Sedimentary basins hosting the Phanerozoic deposits of peninsular India can be broadly categorized into two viz. Gondwana related half grabensand Meso-Cenozoic passive margins. Recent investigations document marine incursions in the former category of basins based on careful analysis of trace fossil assemblage and tide-and wave-originated sedimentary structures. The study of continental carbonates in the Upper Gondwana reveals widespread microbially mediated carbonate formation in freshwater systems, while the mud-dominated fluvial deposits in these basins show unique characteristics of the channel to overbank sediment transfer, related to a balance between sediment flux and erosion.The application of sequence stratigraphy provides a high-resolution analysis of passive continental margin sedimentary succession in Kutch, Cauvery and Jaisalmer basins. The origin of authigenic minerals has been integrated with the sequence stratigraphic framework in several Mesozoic and Cenozoic basins. A thorough biostratigraphic investigation reveals different order of sea-level cycles in the sedimentary deposits of Cauvery and Kutch basins and hyperthermal events in the Cenozoic of Kutch. Distinct ichnological assemblages characterize the transgressive and regressive deposits in Kutch and Jaisalmer basins. Quaternary terrestrial sedimentary records provide a high-resolution palaeoclimatic reconstruction.

“…The depositional conditions of the formation range from middle shelf to upper bathyal. Globally significant episodes of ocean anoxia, OAE‐1c, OAE‐1d, OAE‐2, have been identified in these offshore deposits (Figure ; Govindan, ; Nagendra & Nallapa‐Reddy, ). The Late Albian organic‐rich shales of the offshore Andimadam Formation correlate with the OAE1c.…”

“…Banerjee, Bansal, Pande, et al () reported mineralogical and chemical characteristics of glauconite within the Karai Shale Formation and discussed its stratigraphic implications. The organic carbon‐rich sediments within the offshore equivalents of the Karai Shale Formation possibly records OAE1c (~102 Ma), OAE1d (~99.5 Ma), and OAE2 (93.5 Ma) (Govindan, ; Nagendra & Nallapa‐Reddy, ). Radiometric age determination of glauconite samples in the Karai Shale Formation therefore has the potential for precisely constraining the timing of transgressive deposits onshore and anoxic events (Cretaceous) in the offshore Cauvery Basin.…”

The timing of oceanic anoxic events in the Cretaceous succession of Cauvery Basin: Constraints from ⁴⁰Ar/³⁹Ar ages of glauconite in the Karai Shale Formation

et al. 2018

This study presents 40Ar/39Ar ages of autochthonous glauconites from the lower segment of the onshore Karai Shale Formation of the Cauvery Basin that constrain its age from 100.3 ± 0.7 to 92.6 ± 0.6 Ma. The 40Ar/39Ar plateau ages of the 3 glauconite samples are consistent with the existing biostratigraphic age of Late Albian to Middle Turonian of the Karai Shale Formation. These ages are significant because of the occurrences of oceanic anoxic event (OAE)1d and oceanic anoxic event (OAE)2 in contemporaneous offshore deposits, the Sattapadi Shale and Bhuvanagiri Formation, respectively. Although in the onshore deposits, the glauconite ages mark condensed deposits of the transgressive Karai Shale. As onshore glauconitic deposits may be transitional to organic‐rich black shale deposits offshore in modern and ancient sedimentary settings, the 40Ar/39Ar ages precisely constrains the timing of Cretaceous oceanic anoxic events reported in the Cauvery Basin.
