Abstract

Summary

We study the NE emerged portion of the Asturian Basin, a Permian-Mesozoic extensional basin (NW Iberia) partially inverted during the Cenozoic as a result of a contractional event. A geological map, a 3D model, cross sections, a structural analysis and a 3D photogrammetric study were performed. Our goal is to comprehend the relevance, relative timing and behaviour of the extensional and contractional structures formed during the tectonic events defining its current framework. A Mesozoic extensional episode characterized by fault activity, increase of thermal flow and uplift and a Cenozoic contractional episode responsible for reverse and strike-slip reactivation of old faults and generation of few thrusts and folds occurred.

The information obtained here should assist with the study of worse exposed inland parts of the basin and the seismic interpretation of offshore data. Additionally, understanding the structural configuration of the Jurassic rocks cropping out in the zone might be of interest as an analogue for hydrocarbon industry, given that some of them may be potential hydrocarbon source rocks. Additionally, unravelling their structure is essential considering the recent request for a hydrocarbon exploration permit by an oil company including this area which, in turn, belongs to a state reserve acreage for CO2 storage.
