简介
The West African craton consists of an Archaean or Palaeoproterozoic basement covered by sediments ranging from the Neoproterozoic to the present time. It is entirely surrounded by several Pan-African or Hercynian belts. The old basement is exposed in two shields, and the sedimentary units filled up three main basins: Tindouf, Taoudeni and Volta. The largest one, the Taoudeni basin, is located in the middle part of the West African craton. The Taoudeni basin is made of six different basins or troughs having a non-similar evolution. The structural and sedimentary evolution largely depends on the geodynamic evolution of the neighbouring belts. We have the intention to connect the sedimentary environments and the tectonics events that occurred around the craton. Five main tectonic events have been distinguished: the BI Anti-Atlas event on the northern margin (∼ 685 Ma), the Pan-African I tectonic event on the …
