Depósitos de tsunami en el valle de Agaete, Gran Canaria (Islas Canarias)
Pleistocene marine conglomerates, first interpreted as alluvial-marine deposits, are attached to the walls of the valley of Agaete (NW of Gran Canaria), at 50-7 70 m above sea level. The deposits are 7 to 5 m thick, poor-sorted, clast-supported and formed by heterogeneous, angular to rounded, volcan...

| Sumario: | Pleistocene marine conglomerates, first interpreted as alluvial-marine deposits, are attached to the walls of the valley of Agaete (NW of Gran Canaria), at 50-7 70 m above sea level. The deposits are 7 to 5 m thick, poor-sorted, clast-supported and formed by heterogeneous, angular to rounded, volcanic clasts and fossils, never found in growth position and ofcen broken. The basa1 conracts show reaping features of the substratum and internally present two or more layers,with reverse grading. Distribution, altitude and sedimentary structures of these deposits suggest that they were originated by tsunarni waves, the rnost probable source being the Güimar giant landslide (east coast of Tenerife, <0,84 Ma). |
