The aim of this study is to contribute to the detection and identification of hydrothermal alteration zones in Variscan granites using magnetic susceptibility. The studied area is located in the North-western of Portugal and is characterised by the occurrence of Au mineralizations in quartz veins hosted in Variscan granites. Three different granite facies were studied, using two methodologies: (i) measurements, in situ, of magnetic susceptibility using a portable susceptibility meter (TerraPlus KT-10), allowing th...
