Program	Gran Canaria is a magnificent textbook in volcanology owing to excellent exposures along deeply incised canyons and a wide spectrum of emplacement mechanisms and magma compositions. The overall theme of the 8-day excursion (May 22-29) is a synoptic presentation of the temporal, structural, compositional and volcanic evolution of a very complex oceanic island during some 16 m.y..
Major topics	Miocene phase: Shield basalts, including hands-on dike swarm; thick piles of some 25 rhyolitic (14-13.3 Ma) and ca 20 phonolitic ignimbrites and thick lavas erupted between 13.2 and 9 Ma including spectacular compositionally zoned (rhyolite to basalt) cooling units; structures of high-T peralkaline ignimbrites; a textbook 20 km diameter caldera including magnificently exposed hands-on caldera wall and cross section through caldera interior (huge cone sheet dike swarm and intrusive syenites). Late Miocene – Holocene phases: Major post-erosional large Roque Nublo stratocone: alkalic mafic to evolved lavas, phonolitic domes and volcaniclastics topped by spectacular debris avalanche deposits; thick piles of Late Pliocene (melilite) nephelinites, some rich in peridotite nodules, and basanites; Late Holocene basanitic tephra cones, maar craters and their deposits.
