Abstract
En este trabajo se presentan nuevos algoritmos de cálculo de edad para
muestras del Pleistoceno superior y Holoceno a partir de los valores D/L del
ácido aspártico del ostrácodo Cyprideis torosa en la Península Ibérica para
zonas con distinta temperatura media anual: Bañolas y Padul con una temperatura
de 16ºC, y Cartagena con una temperatura de 18ºC. La mejor aproximación
matemática para Bañolas y Padul relaciona la raíz cuadrada de la
edad con los valores D/L Asp, mientras que para Cartagena la ecuación con
el coeficiente de correlación más alto fue para la edad con la relación D/L
Asp. Estos algoritmos permitirán datar localidades de hasta 30 ka de la Península
Ibérica con evidentes aplicaciones paleoambientales, geomorfológicas
y paleontológicas
Age calculation algorithms for aspartic acid D/L values analysed in the ostracode species Cyprideis torosa for Upper Pleistocene and Holocene were determined for two different environmental scenarios in Iberian Peninsula: areas with a mean annual temperature of 16ºC (Bañolas and Padul), and those with a mean annual temperature of 18ºC (Cartagena). The best mathematical approach for Bañolas and Padul was found to be that which correlates the square root of time and Asp D/L values, whereas for Cartagena the relationship between age and Asp D/L provided the highest correlation coefficient. Using these algorithms sites up to 30 ka will be able to be dated and, therefore, with application to paleoenvironmental, geomorphological and palaeoentological studies
