Determinación de la dirección de inyección filoniana, mediante el análisis de la anisotropia de la susceptibilidad magnética (ASM)

Abstract

The AMS thecnique allow us to make a quick and precise determination of the magmatic flow plane and the magmatic flow direction, inside dykes and in their igneous host rock. Once calculated, the existing relationships between these two parameters allow us to establish if the stress system which originated the dykes emplacement coincides with that contributing to the emplacement of the pluton where they are included or on the contrary, has an origin related with later regional stresses. In this article, we have studied three aplitic dykes intruding in the La Alberca-Bejar granitic area. Each of them represents one of the three main types of dykes existing in the granitic massifs
