Crozet Islands
The Crozet Islands (French: Îles Crozet; or, officially, Archipel Crozet) are a sub-antarctic archipelago of small islands in the southern Indian Ocean. They form one of the five administrative districts of the French Southern and Antarctic Lands.
Geography
Not including minor islets or rock reefs etc., the Crozet group consists of six islands. From west to east:
(1) Group of two major islands (Grande Île—Big Island, and Petite Île—Little Island) and about 20 pinnacle rocks.
The Eastern and Western Groups are 94.5 kilometres (58.7 mi) apart (from Île des Pingouins to Île de la Possession)
The Crozet Islands are uninhabited, except for the research station Alfred Faure (Port Alfred) on the East side of Île de la Possession, which has been continuously manned since 1963. Previous scientific stations included La Grande Manchotière and La Petite Manchotière.
Geology
Analysis of magnetic anomalies on the sea floor indicates that the Crozet Plateau formed some 50 million years ago. The islands are of volcanic origin, and basalt. Rock samples indicate volcanic origins going back to at least 8.8 million years.
