Fases de karstificación y sedimentación endokárstica pliopleistocenas en el mediterráneo occidental: evolución de la Cueva de Nerja (Málaga, sur de España)
(Sociedad Geológica de España, 2001)Evidence of several phases of karstification and sedimentation in Nerja Cave (Malaga, southern Iberian Peninsula) is pointed out. The mentioned phases could be representative of the Plio-Quaternary endokarstic evolution ... -
Interpretación geocronológica de la karstificación en el entorno del Sistema Central español a partir de los yacimientos paleontológicos asociados
(Sociedad Geológica de España, 2001)A review of previously published palaeontological data, jointly with new discovered fossils, allowed to stablish that the older fossils into detritic endokarstic deposits in the studied area are of Lower to Medium Pleistocene ... -
Procesos de karstíficación polifásica en las canteras de Crema Marfil (Pinoso, Alicante). Aplicación a la explotación de rocas ornamentales
(Sociedad Geológica de España, 2001)Complex speleothem networks have been recognised in the quarries of the commercial marble Crema Marfil (Paleogene limestones, Monte Coto Pinoso, Alicante). The characterisation of these speleothems (mineralogy, petrography, ... -
Algoritmos de cálculo de edad del ostrácodo Herpetocypris reptans (Baird) a partir de ratios de racemización de aminoácidos
(Sociedad Geológica de España, 2001)Age calculation algorithms for D/L ratios of four amino acids (alanine, aspartic acid, phenylalanine and glutamic acid) analysed in the continental ostracode species Herpetocypris reptans (Baird) were determined for southern ... -
