Tectònica extensiva d'edat juràssica a l'illa de Cabrera (Balears)

Abstract

Jurassic extensional tectonics caused the breakupof the liasic carbonate shelf and the deepening of thepelagic basin at Cabrera (Balearic Islands) duringDogger, Malm and Eearly Cretaceous. As a result ofthis extensional event we found an angular unconfor-mity of the pelagic rocks over the shelf carbonates,the presence of olistolites and olistostromes in thelower part of the pelagic sequence, and a synsedimen-tary system of conjugate normal faults.
