The azimuths of isoanomaly lines of strong magnetic anomalies of total intensity, discovered during a cruise of H.M.S. Owen in 1962 in the eastern Somali basin, Indian Ocean, were investigated on a cruise of R.V. Chain in 1964. Forty-eight azimuths were determined, having an average bearing of 295°. Compilation of this result with magnetic information from studies from H.M.S. Owen and R.R.S. Discovery indicate that a magnetic lineation (305° to 295°) occurs over a broad region (at least 600,000 km2) of the western Indian Ocean. This lineation may become an important key in determining the structure and geologic history of the western Indian Ocean.
