Crozet Basin

Crozet Basin

 

a submarine depression in the southern Indian Ocean. The Crozet Basin is separated from adjacent basins by the West-Indian and Mid-Indian ridges in the north and the Crozet Plateau and Kerguelen-Gaussberg Ridge in the south. Broken hilly relief predominates at the bottom of the basin; flat and undulating accumulative plains appear only in the south-western section. Maximum depth, 5,500 m. Sediments are red deep-water clays, replaced along the edges of the basin by foraminiferous silts.
