Presence de masses de materiel triasique englobees dans les marnes miocenes au sud de la Sierra de Ricote (province de Murcie, Espagne)

Abstract

Abstract The Sierra de Ricote, a part of the Subbetic zone of southeastern Spain, is made up of intensely deformed limestone, dolomite, and other rocks of Mesozoic age. The adjoining Murcie basin is occupied by Miocene limestone and sandy blue marls. The limestone crops out as a hogback ridge against the south flank of the Sierra de Ricote, and the overlying marls to the southeast contain interlayered, poorly-stratified deposits of Triassic marl, gypsum, dolomite, and ophite of Triassic age in blocks up to 60 centimeters in diameter. These deposits represent mudflow masses of Triassic rocks from the Sierra de Ricote that were carried out to the edge of the Miocene sea. They probably represent tectonic movements during the Vindobonian (Miocene).
