Aminocronoestratigrafía e historia térmica de los depósitos cuaternarios de las Islas Canarias (España). Resultados preliminares de la Isla de Lanzarote

Abstract

This paper deals on the first results of an Amino acid racemization dating campaing carried out on coastal and archaeological mollusca deposits of Lanzarote and Gran Canaria islands (Canary Islands, Spain). First results pointed out to a marked difference into amino add kinetics, when compared with Iberian Peninsula one: leucine, Al isoleuclne and aspartic acid racemizate faster (100%) than in the Iberian Peninsula gastropod samples. Glutamic acid and phenilalanine racemizate much more faster and ages obtained, by applying Iberian Peninsula algorithms, are 500% older than those obtained through radiometric methods. Current Mean Annual Temperature calculated values are between 14 and 17°C, being between 11 and 14°C for the Iberian Peninsula
