Abstract: Although Peninsular Malaysia comprises of 25% Paleozoic black shales, these shales have very little published literatures on their mineralogical content. This study employs the use of X-ray diffraction analyses to characterize the mineralogical composition of the Belata Black shales. The findings of the study indicate that the black shales of Belata Formation are dominated by felsic minerals such as quartz and feldspars. Minerals such as muscovite, calcite, pyrite, kaolinite and chlorite are also present, and this may indicate a felsic source rock for the shales. The study of the source of sediments helps in revealing the processes they have gone through and may together be used with the weathering, transport, deposition and burial history of the sediment to analyze their thermal maturity.
