abstract: Shale deposits from Belata Formation outcrops were examined geochemically and mineralogically to establish their paragenesis and, subsequently, to identify factors that govern their depositional environment. Fifty representative samples were examined through SEM/EDX, XRD and XRF. The findings show the mineralogical composition was abundant in quartz, with pyrite and calcite in trace amount. Zr�TiO2 bivariate diagram showed predominantly felsic and intermediate igneous rocks, suggesting that the shales may be coming from the hidden basement rocks of Peninsular Malaysia. The diagenetic controls on the geochemistry are suggested by the changes in compositional trends. The samples exhibit CIA values ranging from 62.2 to 80.2, and PIA values ranging from 65 to 100. According to the V/Ni, Ni/Co, and V/Cr ratios, these black shales were formed in a suboxic environment. Additionally, the high V/Ni ratios (1.47) point to a marine source for the organic content that gives the shales their dark color. The paleoclimate during deposition was interpreted to be semiarid to warm. The black shale samples are inferred to have originated from a passive margin tectonic setting that followed continental collision and rifting stages of the foreland basin development phase of Peninsular Malaysia based on geochemical proxies and associated diagrams. © 2023 Taylor & Francis Group, LLC.
