The Jordanian oil-shale deposits are marinites of Late Cretaceous (Maastrichtian) to early Tertiary age. A number of deposits are in grabens and some may prove to be parts of larger deposits, such as the Wadi Maghar deposit that is now considered to be the southern extension of the Attarat Umm Ghudran deposit. The deposits listed in table 5 …

Oil shale deposits in Ethiopia can be used for production of oil and gas. Introduction. The availability of energy at a reasonable cost has always been a pre-condition for industrial growth, economic and social progress. Owing to the present world wide energy crisis, low-grade fuels (oil shale, coal, tar sand, bitumen, etc.) have become an ...
