Geologic map of the Valencia del Ventoso Variscan igneous complex (SW Iberian Massif, Spain): an example of multi-stage intrusion building by contrasted magma compositions

A map of the areal distribution of lithotypes within the Valencia del Ventoso igneous complex (ca. 130 km 2 ) is presented. The complex is located in the southern Ossa-Morena Zone of the Iberian Massif (Variscan Foldbelt, Spain). Field and laboratory data reveal an intricate geological context resul...

Zusammenfassung:A map of the areal distribution of lithotypes within the Valencia del Ventoso igneous complex (ca. 130 km 2 ) is presented. The complex is located in the southern Ossa-Morena Zone of the Iberian Massif (Variscan Foldbelt, Spain). Field and laboratory data reveal an intricate geological context resulting from multiple, compositionally contrasted, melt pulses emplaced over a short time period. According to field relationships and lithotype characteristics, four main plutonic intrusions and two dyke swarms are discerned within the complex. Firstly, three small (
