Geology of Mauritius

The geology of Mauritius and Rodrigues is comparatively recent. The oldest rocks on Mauritius are only 10 million years old and 1.54 million years old on Rodrigues Island. The mafic basalts of the two islands formed in relation to the hotspot that generated the Deccan Traps and coral reefs built on the volcanoes forming non-volcanic sediments.
