Abstract
RECENT seismic refraction experiments made in connexion with the International Indian Ocean Expedition have confirmed that the shallow Seychelles Bank has crustal structure of a continental type and represents an isolated continental fragment in the middle of the northwest Indian Ocean1,2. The late Precambrian granites exposed on the central islands of the Seychelles group have been shown to be cut by two sets of dolerite dykes which are of a Precambrian and early Tertiary age, respectively3,4.
