Registro de los cambios del nivel del mar durante el cuaternario en las Islas Canarias Occidentales (Tenerife y La Palma)
Deposits and erosional marine features representing Quaternary interglaciar interstadials have been analyzed based on geological mapping, sedimentological and paleontological studies. Isotopic measurements and aminoacid racemization dating have been used for chronological purposes. The most complete marine sequence consists of five marine terraces at elevation between 0 m and 18 m above mean sea level (asl) in Tenerife, where deposits of the Last Interglacial (OIS 5e) include Strombus bubonius and "Senegalese" fauna. For La Palma only preliminary results are presented, but two clear marine levels can be distinguished in the Northeast coast at elevation between 0 m and 4 m asl; the most recent is Holocene, and the oldest, probably, developed during the Last Interglacial. The rate of vertical movements for the last ~ 135,000 years has been calculated for both islands. The values show a gently subsiding trend in Tenerife and a gently uplifting trend in La Palma.
