      The Sultani oil shale (OS) deposit is considered as a major fossil fuel source in Jordan. Applying various petrographic and geochemical techniques, this paper aims to study the Sultani OS geochemical and organic petrographic features. Results show that Sultani OS is a bituminous limestone consisting of very fine-grained matrix with rippled micro-laminated texture and muddy material of ?PaperID= Shale-normalized REE (North American Shale Composite, McLennan, ) plots for francolite from sedimentary phosphorites, grouped by geologic patterns for francolite are consistent for any particular time, which indicates that geologic age is a predictive tool for the assessment and exploration of phosphorite-hosted REE deposits (modified from Emsbo et al., ).
