| Sumario: | This work analyses, from the structural point of view, the granite dyke swarm in the R onda area. Structural features of granite dykes from outcrop to microscopic scale show that their intrusion is controlled by the emplacement of the peridotites over the underlying crustal rocks and prove that granite dyke swarm is not placed randomly. Actually, the orientation of deformed and undeformed dykes provides an indirect but useful tool to determine the kinematic criteria of the hot emplacement of the Ronda peridotites, especially in areas where the ultrabasic rocks are extremely sepentinized. Finally, we also discuss the origin of the granite magma concluding that the continental crust is the most likely source |
