Abstract
Geochemical mapping has been carried out in Goa using soil/laterite and stream sediment as media. The geochemical maps for U, Th, Nb and Ta show a conspicuous pattern in the NW part of Goa. The anomaly axis shows a NE-SW trend which is across the formational trend. The nickel and copper distribution around Usgaon area, east of Ponda, have indicated anomalous signature in the northern continuation of the Usgaon ultramafic complex.
