This book provides a review of Azerbaijan water reserves and main economic deposits (both hydrocarbon and hard) and describes the integrated application of geophysical methods (land, airborne, shipborne and satellite) for studying near-surface and environmental features and regional tectonic-geophysical zonation as well as the study of deep structures in the search for hydrocarbon and hard (polymetallic, copper, gold-bearing, iron-ore, magnetite, etc.) deposits. It particularly focuses on the geophysical examination of seismic activity in the region related to the interaction of the Afro-Arabian and Eurasian lithospheric plates.
