Abstract
Publisher Summary This chapter discusses the structural evolution of the basins of northwest Africa. The Tindouf basin is the most westerly of the Saharan basins. It is elongated east to west. Its western edge is truncated by the cretaceous Atlantic coastal sag basin in western Sahara. It is closed off some 700 km to the east in western Algeria. The basin is asymmetric in cross-section with a steep northerly limb and a gentle southerly limb. It is infilled by some 8 km of sediments of Cambrian to Carboniferous age that broadly conform to the pan-Saharan stratigraphy. The Reggane basin lies between the Tindouf and Ahnet basins. It is elongated northwest to southeast, with a length of some 350 km and a width of some 150 km. Like the Tindouf basin, it is also asymmetric, with a gentle southwestern limb that dips gently off the Reguibat massif, and a steeper northeastern limb that is bound by the Ougarta range.
