| dc.description.abstract | ABSTRACT: The PreguiƧa and Vila Ruiva mines, located in the Ossa Morena Zone, Beja district, were explored for Fe-Zn-Pb in the early and mid-20th century. This study aims to reassess their mining potential by creating geochemical maps using modern exploration techniques combined with petrographic and mineralogical analyses. These maps resulted from field measurements obtained by portable X-ray fluorescence (XRF-P) equipment. The geochemical mapping shows that the Zn, Pb, and Fe anomalies correspond to the waste rock piles presenting, however, variations in their spatial distribution. Spatially concordant anomalies of Fe, Co, Cr, and V were detected in the soil NW of the PreguiƧa mine. | eng |
| dc.description.abstract | RESUMO: As minas da PreguiƧa e Vila Ruiva, localizadas na Zona de Ossa Morena, distrito de Beja, foram exploradas pelo seu conteĆŗdo em Fe-Zn-Pb no Ćnicio e meados do sĆ©culo XX. Este estudo tem como objetivo reavaliar o seu potencial mineiro atravĆ©s da criaĆ§Ć£o de mapas geoquĆmicos com o auxĆlio a tĆ©cnicas modernas de prospeĆ§Ć£o, complementados com anĆ”lises petrogrĆ”ficas e mineralĆ³gicas. Estes mapas foram gerados com mediƧƵes obtidas por equipamento portĆ”til de fluorescĆŖncia de raios-X. A cartografia geoquĆmica mostra que as anomalias em Zn, Pb, e Fe correspondem Ć s escombreiras das minas apresentando, no entanto, variaƧƵes na sua distribuiĆ§Ć£o espacial. Foram detadas anomalias espacialmente concordoantes de Fe, Co, Cr, e V a NW da mina da PreguiƧa. | por |
