Tarso_Toon
Tarso Toon (sometimes also known as Tarso Toh;[2] "Tarso" means "high plateau".[3]) is a volcano in the central Tibesti mountains.[4]
The volcano reaches a maximum height of 2,575 metres (8,448 ft) and a width of 21 by 19 kilometres (13 mi × 12 mi), covering a surface of 600 square kilometres (230 sq mi). It also features a caldera 11 by 12 kilometres (6.8 mi × 7.5 mi) wide,[1] with a gap on its northern side.[4]
It was active in the Miocene,[5] developing over older ignimbrites with tholeiitic rocks. Later, felsic volcanic rocks were emplaced within the caldera and the Voon ignimbrite buried parts of the tholeiite.[6]
