Intra-Conference Field Trip. Natural Park of La Garrotxa volcanic field: magmatic vs phreatomagmatic activity. The role of the basement to control the eruptive dynamics. 7th international MAAR CONFERENCE

Abstract

All the attendees to the Conference will visit the Natural Park of la Garrotxa Volcanic Zone. The volcanic landscape of La Garrotxa is one of the most singular scenic areas of Catalonia, a montane landscape articulated by the rivers Fluvià and Ter that possesses a series of outstanding morphological features generated by the area’ s Quaternary monogenetic volcanism. The first stop of the field trip is a wonderful view of the Castellfollit de la Roca basalt cliff, which consists of two superimposed lava flows with well-developed columnar jointing. Of note too is the aesthetic and visual effect of the urban architecture of the Medieval village of Castellfollit de la Roca sits atop the volcanic outcrop
