Lusitanian basin fieldtrip - Portugal

Tiago Cunha

Senior Petroleum Geochemist / Basin Modeller

IGI in collaboration with Geo Logica (Portugal) led a stimulating fieldtrip to the Lusitanian Basin (west Portugal).

We visited a wide-range of outcrops that expose the elements of the Jurassic-Cretaceous petroleum systems in a variety of depositional environments, together with high-quality examples of rift and inversion tectonics, halokinesis and igneous features. The Lusitanian Basin, although not explored for hydrocarbons, provides excellent proxies for the Petroleum System of the Central-North Atlantic and the North Sea-Norwegian Sea regions. You can find more details about the fieldtrip in the Geo Logica website (https://www.geologica.xyz/petroleum-systems).
