# The "eye of Africa" (Richat dome, Mauritania): An isolated Cretaceous alkaline–hydrothermal complex

Guillaume Matton, Michel Jébrak, 2014. _Journal of African Earth Sciences_ 97: 109-124.

Petrological and structural synthesis of the Richat complex: a bimodal tholeiitic suite cut by carbonatite and kimberlite, a low-temperature hydrothermal event that made the central karst-collapse breccia, and a piston-like collapse of the centre.

## What it's used for here

Cited for the full igneous suite (gabbro ring dikes, rhyolite maars, carbonatite, kimberlite), the hydrothermal event, the 20–30 m relief of the ridges and the inferred 104–94 Ma age of the complex.
