Pan African orogeny; Niger, Air; Niger, Tuareg Shield
Abstract :
[en] Concepts developed in the recently published model of the Air region as a collage of three displaced terranes integrated in a single geodynamic model lead to the proposal of a terrane map of the Tuareg shield. The 23 terranes recognized are separated by subvertical strike-slip megashear zones that can be traced for hundreds of kilometres, or by major thrust fronts. Some of these boundaries have ophiolitic assemblages or molassic deposits
