ABSTRACT:

Groundwater occurrence and its precise mapping in continental flood basalt (CFB) provinces has been a partly resolved subject which necessitates high resolution hydrogeophysical investigations. In CFBs, the aquifer becomes complex owing to multi-layered lava flows separated by intertrappean and irregular pattern of lineaments which govern the regional hydro-dynamics. One of the largest CFBs, covering an area exceeding 500,000 sq km, are found in the 65 Ma Deccan Traps (DT), India. Locating groundwater resources in DT is challenging and requires high resolution mapping tools to precisely delineate the hydrogeological regime in basalts and connecting pathways. To establish an effective methodology for this purpose, an area admeasuring 372 sq km near Nagpur, central India was selected where the basalts lie over early Permian Gondwana formations. The repository consists of supplementary data of pumping test (aquifer test), exploratory wells details, and geophysical VES data generated form Deccan Volcanic Province at Nagpur, India
