Geophysical investigations off Vijaydurg bay, Maharashtra, west coast of India
MetadataShow full item record
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 level of 3 m in sand covered zones. The extension to the offshore of the existing river channel is also noticed. Seismic profiles display 5 major reflectors which match well with the strata as reported in the bore hole log along the coast consisting of clay, sands, sands and boulders (murrum and sand), altered traps and trap basement. Presence of some faults and intrusions along the reported weak planes, oriented in N-S,NNE and NW-SE has been established on the basis of seismic and magnetic investigations.
