Características geológicas de la Sierra de Quibas (Abanilla, Murcia). Su relación con un yacimiento paleontológico pleistoceno

Abstract

The Sierra de Quibas is mainly a Lower Jurassic carbonated relief. Its main structure is a klippe of Middle Subbeticon Southern Prebetic. The internal structure is a NE-SW anticlinorium. Detailed geological mapping (E. 1:25,000) has pointed to anomalous folds (almost N-S) caused by the halokinétic action ofTriassic materials. Also has been detected a Neotectonic activity starting in the Upper Miocene with almost N-S stresses which have reactivated some faults; the N-S faults previously compressive are now distensive.

In the SE edge of the Sierra de Quibas there is an important Pleistocene paleontological site in a karstic cave filled up with reddish detritic material within the Lower Jurassic dolomites, controlled by NE-SW faults
