摘要

Jinfeng (previously known as Lannigou) is the largest known Carlin-type gold deposit in the Yunnan-Guizhou-Guangxi triangle area of southwestern oft-com:office:smarttags" />China. Arsenian pyrite is the most important Au-bearing mineral, and silicification with quartz veins is the well-marked hydrothermal alteration. The trace elements of arsenian pyrites, vein quartz and fluid inclusions in these minerals were analyzed by ICP-MS in this paper. The results show that in contrast to wall rocks and upper crust, the arsenian pyrites are enriched in chalcophile elements, but depleted in V, Sr and HFSE.
