Toussidé
Encyclopedia
Toussidé is a potentially active volcano, the westernmost volcano
of the Tibesti Mountains
of Chad
. It has an elevation of rises 3265 m (10,712 ft) above sea level. The peak is almost centered within the black shape that has tentacle-shaped lava flows extending down the western flank. The volcano’s base measures approximately 90 km in diameter. The light brownish area surrounding the peak shows a distinctive radial drainage pattern that is quite common for stratovolcano
es as the terrain falls away from the main peak. The depression southeast of the volcano measures approximately 8 km in diameter and 1000 m in depth. The white base is caused by an accumulation of carbonate
salts, creating this soda lake of Tibesti. With the exception of small vents that emit gasses and a few hot springs that continue to deposit minerals at the surface of the crater floor, little volcanic activity presently occurs in this region.

Tibesti Mountains
The Tibesti Mountains are a range of inactive volcanoes located on the northern edge of the Chad Basin in the Borkou- and Tibesti Region of northern Chad. The massif is one of the most prominent features of the Central-Sahara desert and covers an area of approximately 100,000 km². The northern...

Stratovolcano
A stratovolcano, also known as a composite volcano, is a tall, conical volcano built up by many layers of hardened lava, tephra, pumice, and volcanic ash. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile and periodic, explosive eruptions...
