Summary of role of research team Permo-Carboniferous volcanism in the Iberian Peninsula occurs mainly in the Pyrenees and in the NE part of the Central System and the Iberian Ranges.
Volcanism ranges from basic to acid in composition.
In the Cantabrians Early Stephanian marine turbidites are overlain by Late Stephanian continental conglomerates which brackets the timing of major uplift. The thickness of the Stephanian succession may reach 8000m, greater than anywhere else in the world. Palaeontological data indicate that the interval between uplift and erosion of the metamorphic rocks and the volcanism was very short. The high T low P metamorphism in the Pyrenees was probably caused by the input of mafic mantle-derived magmas into the deep crust. During the past ten years the Madrid group has initiated a major interdisciplinary study of volcanism in the Iberian peninsula, focussing on the relationships between the geochemical characteristics of the magmatism and its geodynamic setting.
