| 摘 要： | 通过系统采样分析,运用格里戈良分带指数法,探讨了青海果洛龙洼金矿床原生晕垂向分带特征。果洛龙洼金矿床元素分带序列由浅到深为:Au-Pb-As-Ag-W-Co-Cu-Bi-Hg-SbZn-Sn-Ni-Mo。金矿床的矿上晕元素Au、Pb、Ag集中于该矿床的最上部,尾晕元素Sn、Ni、Mo在该矿床下部富集,矿上晕元素与尾晕元素按照理论金矿床垂向分带规律分布,代表了该矿床主成矿期的元素分带特征,而在主成矿期形成的位于矿床最上部的前缘晕元素分布空间已被风化剥蚀。结果表明,金矿床的前缘晕元素As、Hg、Sb,和矿上晕元素Cu、Zn以叠加晕的形式穿插于矿上晕元素及尾晕元素之间,反映了该矿床成矿具有两期次叠加成矿的特征,矿床深、边部找矿工作应围绕这两期成矿作用形成的矿化富集带进行。

| Abstract: | Abstract: This paper describes the vertical zonation of primary halos in the Guoluolongwa gold deposit of Qinghai Province through systematical sampling and analysis using the C·B·Gregorian's zoning index method. The vertical element zonation of the deposit from shallow to depth is in the sequence of Au-Pb-As-Ag-W-Co-Cu-Bi-Hg-Sb-Zn-Sn-Ni-Mo. The elements of Au, Pb and Ag are concentrated in the top of the deposit, and the elements Sn Ni and Mo as the tail indicator elements are rich in the bottom, representing the normal element zonation of the main metallogenic age, and the distribution space for head halo elements of the main metallogenic age has been eroded. As Hg and Sb as head halo elements, Cu and Zn as ore halo indicator elements in theory, were intercalated in the space for ore halo and tail halo of the ore deposit, reflecting two ages of superimposed mineralization. The future prospecting of the deposit should consider this superimposed mineralization enrichment zone as targets. |
