The Seychelles—tiny little islands, remote location, beautiful coral beaches. Few destinations could hold more allure as prototypical tropical islands. Yet the allure of the Seychelles for geologists is not their nature as oceanic islands; on the contrary, geologists are fascinated by the Seychelles because they are so very un-oceanic in nature.

The Seychelle Islands. Video hosted on Google. FThe Hawaiian and Polynesian islands started life as volcanoes in the middle of the Pacific; Iceland, Bermuda, and the Azores did the same in the Atlantic. But the Seychelles are not volcanic at heart; they are granitic, and granite is so un-oceanic a rock that its presence virtually defines the existence of a continent.

Seychelles' 115 islands fall under two distinct groups. The tall granite, Inner Islands cluster mainly within the relatively shallow Seychelles' plateau, 4° south of the equator and roughly 1800 km. distant from the east coast of Africa while the low-lying coralline cays, atolls and reef islands of the Outer Islands lie mainly beyond the plateau up to 10° south of the equator. These Outer Islands are divided into five groups: the Amirantes group lying 230km distant from Mahé, the Southern Coral Group, Alphonse Group, Farquhar Group and finally the Aldabra Group, some 1150km from Mahé. There are 43 Inner Islands in all -- 41 granitic and 2 coralline and a total of 72 coralline Outer Islands.
