Abstract
A Detailed study of magnetics and bathymetry was carried out in the Central Indian Basin between latitudes 9°S and 16°30′S and longitudes 73°E and 79°30′E. The observed east-west trending magnetic anomalies are identified as anomalies 21 to 25. The magnetic lineation pattern revealed the presence of a new fracture zone at 75°45′E trending N12°E. This fracture zone runs parallel to the 86°E fracture zone and appears to change its direction south of 20°S latitude. The differential offsets observed in the identified magnetic anomalies across the new fracture zone are explained in terms of the evolution of the triple junction. The study also confirms the strike of the 79°E fracture zone and its southern extension through the study area.
