Abstract

In areas of the Median Subbetic, as in the middle Jurassic of the Sierra of San Pedro in the southwest of the province of Jaen, important outcrops of basic volcanic and subvolcanic rocks appear. In this area the sedimentation, mainly pelagic, has been controlled in part by the doming of the submarine bottom due to hypabyssal intrusive laccoliths. The injection of magma caused the upwards expansion of the marine bottom and the genesis of shallowing-upward sequences and mud-mounds
