Abstract
A partir de la interpretación combinada del estudio gravimétrico, de la cartografía geológica y del análisis de lineamientos en la Imagen Landsat TM, se han establecido en el sector central de Extremadura una serie de unidades delimitadas por alineaciones gravimétricas, confirmando que hay una estructuración en bloques. Los límites aunque irregulares, están marcados por zonas de alta densidad de fracturación, cuya confluencia puede tener gran interés estructural y metalogénico. La interpretación conjunta de los datos y un análisis exhaustivo de las densidades de las rocas han permitido, mdeiante la modelización gravimétrica, proponer la forma y extensión en profundidad de los cuerpos intrusivos aflorantes y subaflorantes de este sector de Extremadura.
As a result of the combined interpretation of a gravity study, of geological mapping and the lineament analysis of TM Landsat Imagery from the central sector of Extremadura region (Western Spain), a series of units delimited by gravity alignment have been established, confirming that here is a structural setting of the area in blocks. The limits, although irregular, are limited by high density fracture zones, whose intersections may have a major structural and metallogenic interest. The integration of the different data, and an exhaustive analysis of the rock densities have permitteted thourgh the gravity modelling of several profiles to obtain the shape, and the extension in depth of the granitic bodies (outcropping and subsurface plutons) which characterize this sector of Extremadura
