Hematite in the sandstone oc-curs as cement and as rounded reworked intra-A common rock-forming mineral found in felsic igneous rocks, pegmatites and metamorphic rocks, muscovite is the lightest-colored member of the mica mineral group. Micas are a group of sheet silicate minerals distinguished by their perfect single cleavage. This cleavage allows mica minerals to be easily split into thin parallel sheets.This hematitic cement, iron hematitic bands, and concretions have been proven from field observations to be of syngenetic origin, where the iron and uranium are co-precipitated with sandstone.
