La cubeta mesozoica de las Columbrets: aportaciones al conocimiento de la estructura del surco de Valencia

Abstract

The reflection seismic profiles of the southwest Valencia trough show that the Neogene Valencia trough extensional basin is superim posed over a NE-SW oriented syncline. This syncline, Paleogene in age, is made up by more than 8 km of Mesozoic and probably Palaeocene sediments and denotes the presence of a thick Mesozoic basin. Folded and strongly eroded during the late Paleogene, this so-called Columbrets basin is interpreted to extend along the whole Valencia trough and, according to oil data, it developed during the major Upper Jurassic-Lower Cretaceous rifting event that affected the eastern part of Iberia
