成層火山 · France · 1090m

Ile de l'Est, the easternmost island in the Crozet archipelago, is seen in this NASA International Space Station image (N to the top). The glacially-eroded volcano contains about a half dozen young scoria cones of possible Holocene age concentrated on its E flank. Cape Itaine forms the small peninsula on the SW side of the island (bottom left), and Abondance Bay is at the bottom center. · 写真: NASA International Space Station image ISS006-E-37992, 2003 (http://eol.jsc.nasa.gov/). · Wikimedia Commons

地質学的概要

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).
