Hansen Machín, Álex Caja Canarias Comisión Interministerial de Ciencia y Tecnología, CICYT (España) Centre National de la Recherche Scientifique (France) Radioisotopic ages Volcanic history Structural history Rift volcanism Nested central volcanoes Teide Volcano Tenerife Canary Islands GSA Journals Online - GSA Journals Online Access Control.mht The Teide and Pico Viejo stratocones and the Northwest and Northeast Rifts are products of the latest eruptive phase of the island of Tenerife, initiated with the lateral collapse of its northern flank that formed the Las Cañadas Caldera and the Icod–La Guancha Valley ca. 200 ka. The eruptive and structural evolution of this volcanic complex has been reconstructed after detailed geological mapping and radioisotopic dating of the significant eruptive events. A set of 54 new 14C and K/Ar ages provides precise age control of the recent eruptive history of Tenerife, particularly Teide Volcano, the third-highest volcanic feature on Earth (3718 m above sea level, >7 km high), and unique in terms of its intraplate setting. The development of the Teide–Pico Viejo Volcanoes may be related to the activity of the Northwest and Northeast Rifts. Volcanic and intrusive activity along both rift zones may have played an important role in activating the gravitational landslide and in the subsequent growth, nested within the collapse embayment, of an increasingly higher central volcano with progressively differentiated magmas. The coeval growth of the central volcano with sustained activity along the rifts led to a clear bimodal distribution in composition of eruptive products, with the basaltic eruptions in the distal part of the rifts and phonolitic and more explosive eruptions in the central area, where the differentiated stratocones developed. Current volcanic hazard in Tenerife is considered to be moderate, because eruptive frequency is low, explosivity is modest, and the eruptive activity of the Teide stratocone seems to have declined over the past 30 k.y., with only one eruption in this period (1150 yr B.P.). This work has been possible thanks to the financial support of the Caja General de Ahorros de Canarias and the Spanish Plan Nacional de I+D+I research project CGL2005–00239/BTE. Financial support was also provided for the geochronological work by the Commisariat à ľÉnergie Atomique and Centre National de la Recherche Scientifique, France Peer reviewed 2008-02-28T09:09:42Z 2008-02-28T09:09:42Z 2007-09 artículo http://purl.org/coar/resource_type/c_6501 GSA Bulletin, v.119; nº 9/10; p. 1027-1051 http://hdl.handle.net/10261/3104 10.1130/B26087.1 http://dx.doi.org/10.13039/501100004794 http://dx.doi.org/10.13039/501100007273 en open 109835 bytes application/octet-stream Geological Society of America |
