Combined interpretation of geology and gravity in the central area of Extremadura (Spain): aplication to mineral exploration

As a result of the combined interpretation of a gravity study, geological mapping and the lineament analysis of TM Landsat Imagery from the central sector of Extremadura region (Western of Spain), a series of units delimited by gravity alignments have been established confirming that there is an 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 interes
