The hypabyssal rocks have been divided into three groups: 1) felsites and granophyres (out of the studied area in this work), 2) calc-alkaline lamprophyres (spessartites), probably upper Permian (253 Ma whole-rock K-Ar age) and 3) upper Cretaceous (76 Ma) alkaline lamprophyres (camptonites). This work provides new cartographic and geochemical data that allow to show the morphology, distribution and dimensions of the intrusions and the presence of a fourth type of differentiated alkaline lamprophyres (bostonites) not previously described in the Catalan Coastal RangesspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/BostoniteCamptoniteLamprophyreCretaceousAiguablavajournal articleopen access
