The Roques de Garcia unit was generated by such an event. 39Ar/40Ar dating has been carried out on different rock types related to this deposit. 1.70-1.40 Ma ages were measured on volcanic matérial involved in the avalanche deposit, 0.43 Ma on a phonolitic dyke cutting this formation. These results bracket the age of the debris avalanche emplacement which could mark either the transition between Cañadas ll-Cañadas III (1.4-1.1 Ma) or Cañadas Illa-Cañadas lllb (0.6-0.7 Ma) volcanic phases}, publisher = {Sociedad Geológica de España}, keywords = {39Ar/40Ar chronology}, keywords = {Debris avalanches}, keywords = {Roques de García unit}, keywords = {Tenerife}, keywords = {Canary islands}, title = {Edades 39Ar/40Ar de los depósitos de Roques de García (Las Cañadas, Tenerife)}, title = {30Ar/40Ar ages of the Roques de García deposits (Las Cañadas, Tenerife)}, author = {Arnaud, N. and Huertas, María José and Cantagrel, J.
