AbstractAbstract
[en] Remote sensing imageries and seismotectonic maps were studied in the light of recently published regional gravity data jointly by NGRI, OIL, GSI and SOl (2006) for accessing the structural fabric of the area to locate suitable site for nuclear power plant. Entire analysis of the data sets has been carried out in Geographical Information Systems (GIS) environment. The study area, Rawatbhata falls well within the Vindhyan Basin bounded by the towns Bundi in the North, Chittaurgarh in the West, Jhalwar in the Southeast and Kota in the Northeast. Interpretation of the arcuate shaped gravity low in the southeast reveals the probable extension of Hindoli Group of Rocks below the Vidhyans and Traps. The selected location is sitting on the gravity high. A gravity gradient of 5 mGal is observed within the 10km buffer zone which is marked in yellow on all the maps. Earlier workers interpreted the thickness of the Vindhyan sediments as 6-7km, based on the deep seismic and gravity surveys, conducted along the Kunjer-Nagaur transect. Study of the seismotectonic maps published by GSI doesn't indicate any seismic activity over the decades. NE-SW trending neotectonic faults and few thermal springs are noticed far away from the study area around 100 km NW of Great Boundary Fault (GBF). Numbers of NE-SW, NW-SE trending major and minor lineaments/faults are present in the region. However, analysis of the geophysical data sets doesn't reflect any such lineaments/faults within 25 km radius. Integrated study of the area helped in evaluating the existing nuclear power plant site.
