Year: 2009
Type: article
Abstract: The lower Permian Hercynian Aiguablava leucogranite (288 Ma) is intruded by a dense vertical dyke \nswarm and a few subhorizontal dykes that fill several joint systems developed during the crystallization \nand cooling of the plutonic intrusions. The hypabyssal rocks have been divided into three groups: 1) \nfelsites and granophyres (out of the studied area in this work), 2) calc-alkaline lamprophyres (spessartites), \nprobably upper Permian (253 Ma whole-rock K-Ar age) and 3) upper Cretaceous (76 Ma) alkaline \nlamprophyres (camptonites). This work provides new cartographic and geochemical data that allow to \nshow the morphology, distribution and dimensions of the intrusions and the presence of a fourth type of \ndifferentiated alkaline lamprophyres (bostonites) not previously described in the Catalan Coastal Ranges
