Abstract
Abstract The Aier crystalline massif, west Africa, is composed of folded, metamorphosed, and granitized Precambrian formations forming an isolated massif which rises above younger sedimentary formations of the adjacent area. The massif is an elongate horst trending north-south between faults 180 kilometers apart. The two oldest series in the complex are separated by a major unconformity; they correspond to the Suggarian and Pharusian of the Ahaggar mountains. The topography has been rejuvenated by large granite intrusions and recent volcanism. Tin, tungsten, and columbite deposits are being exploited in the massif. Its structure is considered favorable to the possible occurrence of uranium and petroleum in the periphery.
