ABSTRACT Oil shale is an organic-rich, fine-grained sedimentary rock, containing kerogen, from which liquid hydrocarbons (called shale oil) can be produced. The oil shale deposits in the Tigray region are found in the northern parts of Ethiopia, Eastern Africa. They are of Upper Paleozoic in age, existing as remnants of the Cretaceous erosion period, underlain by tillites and overlain by sandstones. They were formed during the glacial retreat followed by marine deposition of shales in a basin…

In order to study the log response characteristics of oil shale in Qingshankou formation of the south of Songliao basin, the geology of in-situ mining of oil shale in this area is preliminarily

Mining sector challenges in developing countries, Tigray, Ethiopia and inspirational success stories from Australia

The urge to make wealth, reduce unemployment, and improve the living conditions of its people pushes the Ethiopian Government to regulate the mining legislation to favour investment in the sector.

Water strategies and water–food Nexus: challenges and opportunities towards sustainable development in various regions of the World

The twenty-first century is witnessing an explosion in global population, environmental changes, agricultural land disintegration, hunger, and geopolitical instabilities. It is difficult to manage

Production of Isotropic Coke from Shale Tar at Various Parameters of the Delayed Coking Process

To assess the quality of the resulting coke, properties such as the absolute density, yield of volatile substances, ash content, and total porosity were analyzed and the scanning electron microscopy technique was used to confirm the results of the analysis of the formed structure of shale coke obtained earlier.



Geological characteristics and economic evaluation of oil shale deposits in Tigray , Ethiopia

The oil shale deposits in Tigray are widely distributed in the eastern and central part of the region. The oil shale deposits are of upper Paleozoic in age and are found as remnant of the Cretaceous


Oil-shale deposits are found in many parts of the world. They range in age from Cambrian to Tertiary and were formed in a variety of marine, continental, and lacustine depositional environments. The

Fossil fuel energy resources of Ethiopia

Inter-Trappean coal and oil shale-bearing sediments are widely distributed in the Delbi-Moye, Lalo-Sapo, Yayu, Sola, Chida, Chilga, Mush Valley, Wuchale and Nejo Basins. Coal and oil shale-bearing

Depositional environment of Late Cretaceous to Eocene organic-rich marls from Jordan

Oil-shale beds formed under anoxic conditions that were controlled by various local, regional and global factors. The Jordanian oil shales, which were deposited during the Late Cretaceous to

Characterization and Genesis of Some Jordanian Oil Shales

Oil shale in Jordan belongs to the Muwaqqar Chalk Marl Formation (MCM) of the Maastrichtian-Paleocene. Jordanian oil shales are not shale but carbonates. The inorganic constituents are: carbonates,

Adigrat Sandstone in Northern and Central Ethiopia: Stratigraphy, Facies, Depositional Environments and Palynology

In northern and central Ethiopia, continental to shallow-marine siliciclastic sediments of up to 430 m thick are exposed. These sediments are referred to as the ‘Adigrat Sandstone’. This study

Environmental problems in the Estonian oil shale industry

In Estonia technologies for oil shale mining and consuming have been continuously developed for more than 80 years. By March 2006 one billion tonnes of oil shale had been produced in Estonia. Since
