摘要
大水沟碲矿床具有良好的多金属矿集区的区域成矿地球化学背景。研究表明大水沟碲矿床碲成矿物质可能源于深部,且与小金河—箐河等深大断裂有密切联系。
This paper deals with regional geochemical characteristics of the Dashuigou Te deposit in Shimian, Sichuan which are ： geochemical background rich in iron-group elements, as well as Cu, Zn, Hg, Mo Sb, F, Pb 、 Au and Ag with depletion in SiO2 and K2O and the Te deposit lying in the intensive turning of the steep zones in Pb-isotope （V2） isograms and in Te-depleted geochemical background with local Te enrichment （up to 7-8 orders of magnitude）. They suggest that the ore-forming metals might be derived from the depth. The ore-formation should be associated with the Xiaojinhe-Jinghe deep fracture zone.
