Geological summary
Ile de l'Est, the easternmost island in the Crozet archipelago, is a glacially eroded basaltic stratovolcano. A metamorphosed gabbroic complex is cut by a dense network of dikes and cone sheets that fed younger volcanic rocks. The 10 x 19 km island is the oldest of the Crozet Islands, but contains five younger oxidized scoria cones, most of which are on its E flank. The young scoria cones may be Holocene (LeMasurier and Thomson, 1990).
