| dc.description.abstract | At Segura two-mica granite, muscovite granite and granodiorite veins intruded the schist-metagraywacke complex. Aplite and stanniferous pegmatite veins cut granites and country rock. Subhorizontal Sn-W quarz veins and Ba-Pb-Zn quarz veins intruded the country rock and granites. The abandoned mining area was exploited for Sn, W, Ba and Pb until 1953. In soils and stream sediments, the are anomalies of Sn,W, Ba, As and Cu related to Sn-W quarz veins, whereas Ba, Pb and Zn anomalies are associated with the Ba-Pb-Zn quarz veins. Soils are contaminated in As, Sn, B and Ba, and should not be used for agriculture and residences. The highest As contamination is associated with Sn-W quarz veins. The soils contaminated in As mus not be used for commerce and industry. The spring and stream waters are contaminated in As, Fe and Mn. The waters are not drinkable and they may not be used for agriculture. | por |
