Seychelles

Regions

The islands of the Seychelles in the Indian Ocean are part of the granitic Mascarene Plateau which broke off from the Indian Plate about 66 mm years ago at the end of the Cretaceous. This rifting was linked to the Reunion hotspot which is also responsible for the Mascarene islands, including Mauritius, and the Deccan Traps in India.

Offshore seismic data over the plateau has revealed a block-faulted sequence overlain by flat-lying sediments that make up a rift-drift succession. The section reaches at least 6,000m in thickness. Four wells have been drilled to evaluate this basin but no petroleum potential has been identified in these offshore waters sufficient to justify further drilling. Globalshift regards the country as having no oil and gas potential onshore and offshore.
