Mesozoic anomalies in the Bay of Bengal
The analysis of 8200 line km of total magnetic intensity data in the Bay of Bengal, northeastern Indian Ocean, revealed the presence of approximately N30~'E-trending seafloor spreading type magnetic anomalies. These anomalies ...
Subsurface geology of the Bombay Harbour
(Surathkal: KREC, 1989)
As part of engineering pre-design investigations, high resolution geophysical surveys were carried out in and around Bombay harbour, India. The depth in the area varies from dries over the mudflats to about 14m towards the ...
Geology and structure of the astrid ridge, dronning maud land, Antarctica
(American Geophysical Union, 1988)
Regional tectonic trends on the inner continental shelf off Konkan and central west coast of India
Satellite imagery and offshore magnetic data were analysed to correlate regional tectonic elements on the inner continental shelf off Konkan and the adjacent Deccan plateau. Three statistically important lineament trends ...
Geophysical investigations off Vijaydurg bay, Maharashtra, west coast of India
Bathymetry of the bay indicates a smooth gradient in the sandy zone while steep gradient is marked off cliffs and headlands. In general, the results of the wave action have been seen by the presence of undulation to the ...
Marine magnetic profiles from the Direction Bank to the Kori Bank, Western Continental shelf of India
(Geological Society of India, 1986)
Total magnetic field intensity measurements along two parallel NW-SE tracks from the Direction Bank to the Kori Bank show corelatable magnetic anomalies. High frequency positive anomalies observed northwest of Kathiawar ...
Marine geophysical studies off Karwar, West Coast of India
(Geological Society of India, 1989)
Geophysical studies of the southwestern continental margin revealed significant surface and subsurface topographic highs (ridges) trending NNW-SSE to NW-Se beyond the shelf break. Residual magnetic anomaly map depicts ...
Analysis of magnetic anomalies in relation to Placer deposits and basement configuration off Mirya bay, Central West coast of India
The offshore ilmenite placers off Konkan, central west coast of India, have been surveyed by echosounding, shallow seismic profiling, magnetics, and seabed sampling. The magnetic data show two different types of anomalies: ...
Use of shallow seismic surveys in the exploration of nearshore placers off Maharashtra coast, India
Shallow seismic surveys were carried out for 520 lkm in 3 bays viz., Jaigad, Ambwah and Varwada along the Maharashtra coast in the western part of India. In total, 53 traverses were run across the shelf perpendicular to ...
