Abstract
The Iknioun granodiorite (Eastern Saghro, Anti-Atlas) of Ediacaran age displays a regular pattern of magmatic lineations and foliations determined through an anisotropy of magnetic susceptibility (AMS) study. S-sigmoid features outlined by these lineations and top-to-the-SE movements in the adjacent country rocks show that the emplacement of this pluton was related to the E–W-trending dextral transpressive movements previously described in the Saghro inlier. Consequently, this pluton appears as a particularly useful tectonic marker for the Ediacaran evolution of this part of the Anti-Atlas which constituted the northern border of the West African Craton.
