Multiple data parameters required for subsurface area study of the Palar Basin, Tamilnadu

I am a final year MSc Geoinformatics student of  the Centre Of Excellence In Remote Sensing, Bharathidasan University,Trichy, Tamilnadu. I am doing my major project in the topic " Landscape Mapping of Shallow Subsurface in parts of Tamilnadu". For the study purpose, the chosen area is Palar Basin of Tamilnadu.
Now I am working with the resistivity data for subsurface lithology mapping. It would be helpful if I could obtain more data parameters related to the same. Kindly provide me information regarding how to obtain data such as bore hole data, resistivity data, gravity data and other geophysical data available for the study area.
