Abstract
THE Vema Seamount is an isolated volcanic pile which rises from the ocean floor near the centre of Cape Basin at 30° 38′ S., 8° 21′ E., approximately midway between the Walvis Ridge and the South African mainland1. It is approximately 1,500 miles north-east of Gough Island and 2,300 miles south-east of Ascension Island, which lie on the mid-Atlantic Ridge, and 1,500 miles south-east of St. Helena Island, which lies close to the Ridge. Isotopic measurements have previously been obtained for samples from all three localities2,3.
