浙江火山岩区金矿床黄铁矿的找矿矿物学研究

论文给出了中国浙江火山岩区金矿床中黄铁矿的微量元素、形态和物理性质找矿标型特征.例如.(在许多)浙江火山岩区重要金-银矿床中黄铁矿相对富含铅、锌、钼、锡、砷、锑、铋而贫钴,镍、硒、碲:并且S/Se、Ag/Au、Pb/Ni、Se/Te、(As+sb+Bi)/(Se+Te)比值较高,Co/Nj、Ag/Pb、Ag/Zn、Cu/Zn和(Co+Ni)/(Pb+Zn)比值较低,再如含金黄铁矿比不含金黄铁矿的反射率低.总之,黄铁矿的标型性研究对于寻找金矿具有重大的理论意义和实际意义.

ON THE PROSPECTING MINERALOGICAL STUDY OF PYRITE FROM GOLD DEPOSITS OF THE VOLCANIC TERRAIN IN ZHEJIANG PROVINCE, CHINA

In this paper, the prospecting typomorphic characteristics for minor elements, morphology and physical properties of pyrite from gold deposits of the volcanic terrain in Zhejiang province are giyen. In many important gold-silver deposits from the volcanic terrain in Zhejiang, pyrite is relatively rich in Pb, Zn, Mo, Sn, As, Sb, Bi, and poor in Co, Ni, Se, Te; and has higher ratios of S/Se, Ag/Au, Pb/Ni, Se/Te, (As+Sb+Bi)/(Se+Te), lower ratios of Co/ Ni, Ag/Pb, Ag/Zn, Cu/Zn and (Co=Ni)/(Pb+Zn). The reflectance of gold-bearing pyrite, for example, is less than non-auric pyrite. In sum, the study of typomorphism of pyrite is of great theorectlcal and practical signiticance for gold prospecting.
