Abstract


A total of 74 samples of canarian volcanic rocks allows to show the variability of the magmatism. Isotopic relationships (Pb, Sr and Nd) limits the magmatic reservoirs to HIMU and EM2. The existence of sediments in the canarian crust would explain the contamination processes existing in some islands.
The chondritic REE pattern indicates a fractional crystallization process for the canarian magmatic sequence, chemical changes observed in some basic rocks could be related to contamination processes.
