Combined potential field and airborne electromagnetic interpretation to unravel the geological history of the Curaca Valley Region, Bahia, Brazil

Summary

Integrated geological-geophysical interpretation offers a robust way to answer geoscientific questions by providing better and faster decisions on where to explore in a regional context, and ultimately on local-scale targets. In particular, regional scale geophysical datasets can be used in areas of extensive cover and limited outcrop to quickly develop three dimensional geological models that can serve different purposes such as targeting or hypothesis testing via forward modelling. To show these concepts, we present a case study from the Curaçá Valley Cu region in Bahia, Brazil. A large geophysical data set including airborne gravity, magnetic and airborne electromagnetics was used and combined with existing 2D regional geology from different sources to produce a 3D integrated model.
