Análisis mesoestructural automático del diaclasado: programa "Joints". Aplicación a un sector del antepaís Bético
(Sociedad Geológica de España, 1999)Computational methods related with the analysis of fault populations (striated planes) are used currently for the characterisation ofthe deformation in intraplate zones. Although these methods are quite successful, we ... -
Aplicación de índices geomorfológicos de actividad tectónica reciente en el antepaís Bético
(Sociedad Geológica de España, 1999)The application of some geomorphic indices of recent active tectonics in the Meseta Inferior of the Iberian Peninsula has proportioned some interesting insights about of the interdependence between the neotectonic deformation ... -
Aplicación del método DRASTIC para la cartografía de vulnerabilidad a la contaminación del acuffero carbonatado de Torremolinos (Sierra de Mijas, provincia de Málaga)
(Sociedad Geológica de España, 1999)The paper show the results of the aplication of the DRASTIC method for contamination vulnerability assesment in the fissured carbonate aquifer of Torremolinos. The final mapping of the overlay cover using CIS (Arc/info y ... -
Arquitectura de facies holocena del dominio fluvial del Estuario del Río Odiel (S.O. España)
(Sociedad Geológica de España, 1999)Five different lithofades constituted the holocene infilling of the Odiel estuary fluvial domain. These facies have been recognized by a sedimentological study of six drilling cores located along a transverse profile. The ... -
Cálculo automático del desplazamiento en un sector del sistema falla-dique de Plasencia
(Sociedad Geológica de España, 1999)By means of the use of a new methodology of structural analysis, based in the combination of photogrametry restitution technics and geological maps, the dynamics and kinematics of a sector of Plasencia fault-dike system ... -
Características y factores de control del relleno sedimentario reciente en los fondos de la bahía de Cádiz
(Sociedad Geológica de España, 1999)To know the characteristics of the recent sedimentary infilling of the Cadiz bay sea bottom and adjacent continental shelf, a non consolidate recent sediments isopachs map has been made, based on geophysical and submarine ... -
Caracterización de la morfodinámica de la playa de Tres Piedras (Chipiona) mediante el uso de trazadores cromatóforos
(Sociedad Geológica de España, 1999)Fluorescent tracers have been used in a field assessment at Tres Piedras beach (Chipiona) in order to characterise morphodynamic processes, disturbance depth and longshore transport during a single tidal cycle. Native sand ... -
Caracterización de los sedimentos de la plataforma proximal del complejo playa-barrera-lagoon de Corrubedo (Galicia, NO de España)
(Sociedad Geológica de España, 1999)In this paper grain size parameters and calcium carbonate content of subaquatic sediments in front of Corrubedo beach barrier lagoon complex are presented. Sediments are mostly sands. The general distribution pattern shows ... -
Caracterización geoeléctrica de depósitos superficiales en la Antártida Occidental (Isla Livingston, Islas Shetland del Sur)
(Sociedad Geológica de España, 1999)The geophysical study of superficial deposits (mainly gravels) in ice-free areas near the seashore in the South Shetland Islands (Antarctica) allows establishing the possible existence of permafrost and buried ice bodies. ... -
