Composition Of The Floor Afar Triangle

The afar triangle at the foot of the red sea is shaped by newly formed faults that cut unweathered basaltic lava flows on a newly emergent seafloor in an almost totally tectonic landscape.

The southern part of the region consists of the valley of the awash river which empties into a string of lakes along the ethiopian djibouti border. During the third stage sea floor. The barren deserts of the afar triangle constitute a basaltic ocean floor terrain on a divergent plate boundary that is above sea level because it lies over a hot spot. The afar depression is an area of lowland plains split by fault blocks and dotted with shield volcanoes.

That is the earliest of the human clade. It is bound to the west by the ethiopian plateau and escarpment to the northeast by the danakil block to the southeast by the ali sabieh block and to the south by the somalian plateau and escarpment.

The afar triangle is bordered by high areas as shown on the topographic map. Thermal infrared afar triangle ethiopia. Here the upwelling magma is of a characteristic composition low in silica content normally found at mid oceanic rifts. The afar triangle the northern part of which is the danakil depression is part of the great rift valley of ethiopia and is located in the north of the region it has the lowest point in ethiopia and one of the lowest in africa.

Normally geological processes such as the formation of rivers seas and mountains is a painfully slow process but in the afar triangle near the horn of africa this is happening at a staggering rate.

The afar triangle also called the afar depression is a geological depression caused by the afar triple junction which is part of the great rift valley in east africa the region has disclosed fossil specimens of the very earliest hominins. The depression is a plate tectonic triple junction.

The region more and more resembles a sea floor where only the water is missing.
