Abstract : Commercial oil shale is widespread in Jordan occurring mostly in the subsurface. More than 20 localities were reported including Attarat Umm Ghudran (AUM) area. Selected oil shale boreholes drilled in the AUM were sampled, analysed and studied in detail. The purpose is to verify their mineralogical composition and geochemical affinities including trace elements content. They were characterized using the polarizing microscopic, X-ray diffraction (XRD), scanning electron microscopy, and X-ray fluo
