In this paper, we show with examples that cratons involved in intercontinental collisions in a
lower plate position are often affected by orogenic events, leading to the transformation of …

Abstract Both the Borborema Province of NE Brazil and the geological provinces of NW
Africa (the Trans-Saharan Orogen consisted of the Tuareg and Benino-Nigerian shields and …

The Egéré domain belongs to the Egéré-Aleksod terrane (LATEA metacraton), which has
the peculiarity in the Tuareg Shield of being practically devoid of Pan-African batholiths …

In considering the geology of Western Gondwana, this text covers: the Pan-African-
Brasiliano cratons; the Pan-African-Brasiliano fold belts; and amosaic of Pan-African …

The Pan-African belt in central Africa has benefited from the many petrographic, structural,
and geochronological studies in the recent years that have improved our understanding of …

Abstract Concepts developed in the recently published model of the Aïr region (eastern
Tuareg shield; Niger, Africa) as a college of three displaced terranes integrated in a single …

The end of an orogenic Wilson cycle corresponds to amalgamation of terranes into a
Pangaea and is marked by widespread magmatism dominated by granitoids. The post …

Historically, the Tuareg shield is divided into three parts bordered by mega-shear zones with
the centre, the Central Polycyclic Hoggar, characterized by Archaean and Palaeoproterozoic …

After a review of the rock sequences and evolution of the eastern and central terranes of
Hoggar, this paper focusses on the Neoproterozoic subduction-related evolution and …

Three main tectonic events related to Pan-African collision and post-collision evolution have
been identified in Cameroon: i) crustal thickening; ii) left lateral wrench movements; and iii) …
