Study Notes
Geological History of Ethiopia
- Ethiopia's geological history can be divided into eras, including the Paleozoic and Mesozoic Eras.
Paleozoic Era (600 million - 250 million years ago)
- Major geologic process in Ethiopia during this era was denudation followed by peneplanation.
- No significant structural formation took place during this era.
- The Paleozoic era left a gap in rock formation in Ethiopia.
- Denudational activity resulted in the formation of inselbergs (residual features) in some parts of Ethiopia.
- Invertebrates were the dominant life form during this era.
Distribution of Geological Formations
- Paleozoic and Mesozoic formations are found in:
- Central and northern Tigray
- Mettekel, Assossa, Illubabor, and the Abbay Gorge
- Central Sidama, southern Omo, southern Bale, and Borena
- Central, western, and northern Eritrea
Mesozoic Era (250 million - 70 million years ago)
- This era was marked by alternate slow sinking and uplifting of the landmass (Epeirogenesis) of the Horn of Africa.
- The dominant life form during this era was reptiles.
