DOIAbstract
The deformation front of the Neuquén fold and thrust belt (~37°30′S) comprises kilometer-scale basement-involved anticlines, related to development of the Las Yeseras and Pampa Tril thrust systems, connected with awide frontal syncline. The interpretation of more than 70 seismic lines led to the construction of a time-structuremap at top of the Cuyo Group (Middle Jurassic), which shows a structural high east of the Tromen volcanoproduced by the superposition of thick-skinned structures. Moreover, data from 35 oil wells constrain the along-strike variations in structural reliefs. The structural relief of the Las Yeseras anticline increase from north tosouth, between ~1000 m and 2000 m, while the structural relief of the Pampa Tril anticline ...
