2021-10-1 Ethiopian Minerals Ethiopia is indeed the land of plenty, with resources found in abundance throughout its huge and diverse land mass. Geological surveys conducted on minerals in Ethiopia, have shown formations that are believed to contain a vast amount of mineral resources, with proven deposits of industrial minerals, coal, precious metals and metals.

2018-4-28 Rock art in Ethiopia is concentrated in the north, east, south, and south-central part of the country. Previous investigations focused on description and stylistic distribution of the art. A closer look at the mode of rendering the art allows grouping sites into three distinct assemblages: the northern assemblage of paintings and engravings, the eastern and southern assemblage of paintings ...

2015-3-24 The present-day morphology of Ethiopia is linked to the formation of the Afar depression, MER, and Ethiopian plateaus. These events are linked to the impingement of one or more mantle plumes under the Afro-Arabian plate. The elevated topography of the Ethiopian plateaus is the result of profuse volcanic accumulation and successive uplift.

2004-10-28 Causes of Rock Deformation • Stress - pressure placed on rocks • Strain - deformation of the rock • Strength - rock resistance to deformation • Brittle deformation - the rocks break or fracture. Occurs at low temperatures and low pressures. • Ductile deformation - the rocks bend or flow. Occurs at higher temperature and pressures.

Sedimentary rocks such as sandstone and limestone lie unconformably with basalt which resulted from extensive lava flows. The land surrounding the Danakil Depression was once part of the Red Sea. While the water is gone, salt remains in extraordinarily large quantities, and has proven to be a valuable — and fatal — commodity for locals.
