“…However, plots of literature data in the Sr/Rb-Sr/Ba diagram (Fig. 22d) produce large uncertainty; for example, plots of literature geochemical data of Precambrian passive margin pure limestones (e.g., Klein and Beukes, 1989;Bolhar and Van Kranendonk, 2007;Nagarajan et al, 2011;Sen and Mishra, 2015) generally fall in the inland freshwater limestone area (unshown) and those of Phanerozoic margins impure limestones (e.g., Cullers, 2002;Abedini and Calagari, 2015;Madhavaraju et al, 2016) fall across the inland-margins limestone areas, although some of Phanerozoic margins pure limestones (e.g., Cullers, 2002;El Hefnawi et al, 2010;Madhavaraju et al, 2016) fall in the right area (Fig. 22d).…”

“…Estimates of average geochemical compositions of limestone are still lacking and, to our knowledge, only an available estimate of major and trace element compositions of the Phanerozoic marine limestone was given by Condie et al (1991) albeit without any detail. Such estimate is essential for its implications for sedimentary environments and seawater evolution, particularly considering that a wealth of high-quality analyses of limestones (e.g., Armstrong-Altrin et al, 2003;Frimmel, 2009;Madhavaraju et al, 2010Madhavaraju et al, , 2016Fu et al, 2011;Nagarajan et al, 2011;Loope et al, 2013;Qiu et al, 2013;Tian et al, 2014;Sen and Mishra, 2015) have become available in the publications in recent years. As tectonic environment is the primary control on limestone composition as discussed above, the average compositions of limestones of four main tectonic settings, along with some estimate of uncertainty (standard deviations), are calculated (Table 3).…”

Limestone, a major part of the global sedimentary succession, susceptible to post-depositional diagenesis. Studies of limestone geochemistry are essential in the discrimination of tectonic settings of basins in which the limestones were deposited. Six Late Mesozoic and one Tertiary limestone successions of Tibet, western China, that were deposited in oceanic plateau, passive continental margin, active continental margin (fore-arc basin, back-arc basin and foreland basin) and continental inland freshwater basins were analyzed for their major, trace and rare earth element (REE) composition. This geochemical dataset, in combination with the Deep Sea Drilling

The Kaimur Group of the Vindhyan Supergroup has been divided into six Formations in Son valley sector, in Central part of India, i.e., Sasaram Sandstone, Ghurma Shale, Markundi Sandstone, Bijaigarh Shale, Mangesar Formation, and Dhandraul Sandstone. The comprehensive geochemical datasets for all the individual Formations of the Kaimur Group were generated in order to evaluate the source rock composition, weathering history, and provenance. The field observations, petrography, and geochemistry depict the deposition of the Kaimur sedimentary rocks in two cycles—the fining‐upward sequence from Sasaram to Markundi Sandstone, that was followed by the coarsening‐upward sequence from Bijaigarh shale to Dhandraul Sandstone. The petrography, geochemical classification, and A‐CN‐K plot depicts K‐metasomatism in siliciclastics of Kaimur Group. A‐CN‐K systematics and the CIA values (62–85) reveal that the source rocks of the Kaimur Group siliciclastics have suffered high degrees of chemical weathering under warm and humid climate. Zr/Sc vs. Th/Sc and Rb/Sr values depict zircon addition and sediment recycling. Ternary plots based on modal analysis and tectonic discrimination diagrams based on incompatible elements exhibit the deposition of Kaimur siliciclastics in the craton interior /passive margin (Bundelkhand Craton; BC) to recycled orogen (Chhotanagpur Gneissic Complex;CGC). The incompatible elemental ratios and Qm‐F‐Lt plots shows a fluctuation in provenance of the Kaimur Formations in the lower and upper part. The percentage contribution from the two sources was calculated using a simple arithmetic formulae [ Percentage contibution from a single source= Number of comparable ratios/ Total ratios*100]: Sasaram Sandstone = 82% BC + 18% CGC, Ghurma Shale = 76% BC + 24% CGC, Markundi Sandstone = 65% BC + 35% CGC, Bijaigarh Shale = 62% BC + 38% CGC, Mangesar Formation = 61% BC + 39% CGC, and Dhandraul Sandstone = 42% BC + 58% CGC. Tectonics of the hinterland supplying detritus played an important role in deciphering the provenance of Kaimur siliciclastics. The episodic crustal growth and thermal events taking place in Bundelkhand Craton at 1.1 Ga were witnessed by the emplacement of dykes, which led to the increased detrital input from the source (BC). Later on the upliftment of CGC towards the south during Satpura Orogeny‐II led to increase in input to the Formations of Kaimur Group. Petrological, geochemical signatures, and the evidences of change in paleocurrent direction from SSE–SSW to NW–NNW during Kaimur sedimentation strongly support the gradual shift of provenance from BC to CGC.
