“…By examining the elemental composition of rocks, chemostratigraphy provides valuable insights into the depositional environment, diagenetic alterations, and correlation of sedimentary sequences. The use of trace and major elements in chemostratigraphy allows researchers to identify distinct geochemical signatures within rock layers (Birdwell et al, 2017;Chen et al, 2015;Ramkumar et al, 2015;Sano et al, 2013;Turner, Tréanton, et al, 2015;Weissert et al, 2008). These signatures can be indicative of various geological processes, including changes in sediment sources, climate fluctuations, sea and base level variations, and tectonic activities (Pearce et al, 1999;Weissert et al, 2008;Montero-Serrano et al, 2010;Turner, Molinares-Blanco, et al, 2015;Tréanton, et al, 2015).…”

Furthermore, chemostratigraphy enables the correlation of rock units across different locations based on their chemical fingerprints, providing a powerful tool for understanding regional geological history and reconstructing ancient environments.…”

This research aims to determine the chemostratigraphy of the Yolde Formation. The formation has been inadequately studied systematically in the light of chemostratigraphy. The existing works on the formation either lack representativeness in terms of the proxies used or are subjective during their division procedures. From the field studies, five (5) samples of sandstone and shale units of the Yolde Formation were collected. The samples were analyzed for both major and trace elements using an X-ray fluorescence machine. The following geochemical parameters were studied; Al2O3, Al2O3/Fe2O3, KO2/Al2O3, TiO2/Al2O3, CaO, Cr, Rb/Sc, and Zr. From the studies, six (6) chemozones were identified in the Yolde Formation. Transgressive and regressive depositional sequences were observed with a significant sequence boundary of maximum flooding surface which is a time-significant feature. The chemostratigraphic scheme could not only be comparable to the regional sequence stratigraphic scheme but also more objective and higher resolution. This research gives a systematic chemostratigraphic analysis of Yolde Formation, which testifies to the feasibility and potential of the usage of chemostratigraphy for stratigraphic development.

Shale Gas exploration and production plays an essential role in ensuring energy security and economic stability. Tapping these reserves using cost-effective technologies can really change the India's energy supply and value chain. Cambay Shale of Cambay Basin has been proved as the most prominent Indian Shale reserve and in this work an attempt has been made to understand the geographical and mineralogical distribution of this Shale. A sample study on Cambay Shale of North Tectonic Block of Cambay Basin has been ascertained to understand the mineralogy, porosity and maturity with respect to depth. The study involves the use of integrated measurement techniques mainly high-pressure porosity (HPP), scanning electron microscopy (SEM) and Fourier transform electron microscopy (FTIR). Approximately, 13 samples were analysed to understand the mineralogy of this shale and it was observed that it is very clayey in nature with major traces of Illite and minor traces of rutile and kaolinite. The other measurements (i.e., SEM and HPP) were done on two specific samples which confirm the presence of clay-rich porous minerals with high organic matter content.
