(Sociedad Geológica de España, 1996)A palaeomagnétic study have been carried out on the western margin of the México basin. 24 sites from Sierra de Las Cruces were sampled and analyzed in the laboratory. A total amount of 237 samples has been fully demagnetized ... -
Restauración de impactos mineros en zonas semiáridas: el ejemplo de la provincia de Granada
(Sociedad Geológica de España, 1996)Quarries reclamation has been efective since 1982 because of environmental mining laws. Reclamation techniques have been developed quikly during these years. In Grenade province, quarry reclamation is especially dificult ... -
Propuesta de un modelo cronológico para las terrazas de los ríos de la vertiente cantábrica
(Sociedad Geológica de España, 1996)A new fluvial terraces chronology Is proposed for the rivers in northern Cantabrian Range. Six terrace levels were identified and mapped. These have average heights of 2,5; 10; 15; 20; 35; and 63 m above river level. Four ... -
Preliminary magnetostratigraphic data of a Tatarian (Upper Permian) section on the Volga river (Russia)
(Sociedad Geológica de España, 1996)A magnetostratigraphic profile of the uppermost Tatarian (Upper Permian) of a section of continental sediments from Eastern Platform is presented. Around 300 samples across an Upper Permian sequence o f red beds Monastirskoje ... -
