Eclogitas de la banda de Cizalla Badajoz-Córdoba (Suroeste de España).: Datos petrográficos y significado geodinámico

C-type eclogites occur within garnet-amphibolites of the Azuaga gneisses al/ochthon in the Badajoz-Cordoba shear belt (SW Spain). The eclogites were formed under conditions of ca. 600° C, > 13 Kbar, and record a complex evolution related to various espisodes of recrystallization and deformation. The Badajoz-Cordoba shear belt may be interpreted in terms of a polyphase geodynamic evolution involving initial Upper-Proterozoic to Ee!rly­ Cambrian subduction, followed by continental collision, Middle Paleozoic crustal extension and intense Upper Paleozoic (Hercynian) intracontinental ductile wrenching.
