Layered granitoids: Interaction between continental crust recycling processes and
Moita, Patricia; Santos, J. Francisco; Pereira, M. FranciscoIn this paper, field, petrographic, mineralogical, geochemical and isotopic (Rb–Sr and Sm–Nd) information from three areas within the Évora Massif (Iberian Variscan Orogen) is presented and discussed aiming at to unravel the relationships between granitoids and units mapped as migmatites and also to evaluate the interplay between mantle and crustal derived magmas. One of the areas – Almansor – displays a well-d...
Crustal growth and deformational processes in the northern
Pereira, M. Francisco; Silva, Jose B.; Chichorro, Martim; Moita, Patricia; Santos, J. Francisco; Apraiz, Arturo; Ribeiro, CristinaThe aim of this article is to present a compilation of available information on the Évora Massif based on structural mapping, whole-rock geochemistry, recognition of metamorphic mineral assemblages, and geothermobarometry. In our view, transcurrent movements responsible for strong orogen-parallel stretching were dominant and had a major role in the geodynamic evolution of this part of Ossa-Morena zone (southwes...
