| 中文摘要:对大兴安岭中段铜多金属矿床硫化物矿物的微量元素研究表明，虽然该区矿床类型不同，但闪锌矿种属一致，多为铁闪锌矿和含铁闪锌矿，而方铅矿中Sb、Bi、Ag含量却明显不同；黄铜矿中的Co、Ni含量冥想大于黄铁矿中的Co、Ni含量；各类型矿床中方铅矿、闪锌矿、黄铜矿、黄铁矿等硫化物中Ag普遍有较高的含量，反映了大兴安岭中段银处于高异常区，银、金、镉、铟往往具有综合利用价值。 |

| Abstract:The Da Hinggan Mountains constitute an important metallogenic belt in China. The central part of the Da Hinggan Mountains is characterized by relatively intense volcanic plutonic magmatism and metallogencsis. The district has quite abundant Cu, Pb, Zn, Ag, Sn mineral resources. The aim of this paper is to provide comprehensive utilization information and scientific basis for ore deposits in the district on the basis of the studies of minor elements in minerals from polymetallic deposits in the central part of the Da Hinggan Mountains. The authors have detailedly studied minor elements in minerals from several major deposits in the study district. The results show that, although the deposits in the district belong to different minerogenetic types, sphalerites are of the same species, mainly marmatite and ferruginous sphalerite, and that the Sb, Bi and Ag contents of galena in the deposits are different: the Budun Hua deposit. galena is rich in Bi and poor in Ag and Sb ; in the Meng'en Tolgoi, Lian-huashan and Aonao Daba deposits, galena is poor in Bi and rich in Ag and Sb; in the Buyan Nur and Haobugao deposits, Bi, Ag, Sb contents are uniform. In this district the content of galena, sphalerite, chalcopyrite and pyrite is generally higher than that in other districts. Au, Ag, Cd and In are rather high in ore deposits of this district, thus having important value for multipurpose use. |
