Oil shale | Sample type | Organic matter % | Component summary | Internal texture summary | Fisher assay summary |
Ash-Shoubak | Soft bituminous chalk marl | 05.40 | Significant amounts of organic matter; Calcite is the major mineral phase, minor quartz content, traces of fluorapatite and smectite | Very fine-grained matrix, strongly show flow structure and consists mainly of muddy material of cryptocrystalline micrite; Cretaceous forams are abundant. Brown organic matter fills pore spaces | Different oil yielding capacities; Highest for Lajjun and Sultani OS; Lowest for Ash-Shoubak and Jurf Ed-Darawish OS |
