Geochemical Study of Vein-Type Tungsten-Copper Mineralization in Southwest of Shazand

M. Abdi; Majid Ghaderi; N. Rashidnejad-Omran; A. Najafi

Volume 19, Issue 73 , January 2009, , Pages 37-50


  Two cases of tungsten-copper vein-type mineralization have been studied in the Nezam-abad and Deh-hossein areas, in southwest of Shazand. The hydrothermal quartz-tourmaline mineralized veins have different host rocks (biotitic-granite and meta-sandstone). Considering similar ore metals (tungsten-copper-tin-lead-zinc) ...  Read More
