Abstract
Skips/shadow zones in the first arrival travel seismic time data (refractio n) help in delineating hidden low velocity formations sandwiched between tw o high velocity zones. Efficacy of this processing methodology has been suc cessfully tested utilising analog refraction data acquired along a profile located in the Deccan Trap country. The 2D velocity depth details also sugg est probable presence of hidden Sub-Trappean Gondwana formations.
