Resumo
In this work a close dike field has been studied. Emphasis is placed on the composition and fundamental properties of these dikes: their conexión with the regional tectonic and granitic rocks and their genesis and emplacement. According to these data, we have distinguished three main groups: N-S pegmatite dikes, WN W-ESE concordant sheets and E-SE zone dikes. Their sequence has been established and is compared with certain theoretical models for magma intrusion (ROBERTS' model).
