  The Share area occurs within the northern Bida Sedimentary Basin in Nigeria. The focus is on the geological settings, mineralogical and chemical compositions of Share geophagic clays with the aim of inferring their depositional environments, provenance and possible human health implications. The field method include collection of representative samples at appropriate clay stratum and the samples of the geophagic clays were subjected to petrographic, X-Ray fluorescence and X-Ray diffraction analyses. XRD revealed that Geophagic clays are polymineralic and the main reflections of the clay minerals identified were kaolinite, nacrite, gibbsite and dickite. The peaks of other traces are hematite, quartz and pyrite. Geochemical data indicated that geophagic clays composed of SiO2 content ranging from 64.40% to 46.30%, Al2O3 values varies from 36.54% to 20.54%, Fe2O3 values varies from 4.71%.. View More»
