Magnetometrics in the study of sub surface structures of Antarctica margin
During the second Indian Antartica expedition in addition to monitoring time variation in the geomagnetic field components a preliminary ground based magnetic survey was conducted Magneto metric data obtained along six 10 -15 km long profiles, after correction for transient and day- day variability...

Summary: | During the second Indian Antartica expedition in addition to monitoring time variation in the geomagnetic field components a preliminary ground based magnetic survey was conducted Magneto metric data obtained along six 10 -15 km long profiles, after correction for transient and day- day variability are examined in the form of magnetic profiles and anomaly contour map . Qualitative interpretation of data suggests the presence of a north- south trending rift structure on the topographic ridge between 10- 12 E. The structure appears to be northward continuation of rift valley mapped on the continental margin of the Princes Astrid coast. The rift structure appears to terminate against a sharp discontinuity. |
