新疆西凤山金矿床q6含金石英脉原生晕特征
Study on Primary Halo Characteristics of q6 Gold-bearing Quartz Veinsin Xifengshan Gold Deposit, Xinjiang
-
摘要: 在调研西凤山金矿床地质特征的基础上,选择有代表性的q6含金石英脉进行原生晕地球化学测量和异常建模评价工作。对该含金石英脉10项元素的测试分析结果表明:地表Au原生晕强度大于钻孔和坑道Au原生晕强度;q6主矿脉地表原生晕Au2极度清晰,且达到矿体原生晕规模;q6矿脉地表原生晕横向分带总体呈对称分布,并指示了矿体具有向北陡倾的趋势,横向分带序列显示出主成矿元素具异常高强度与较大线规模等特点。该主矿脉中元素的分布及变化规律的研究,对该矿区进一步的矿体追索与工程布置具有指导意义。Abstract: Based on the investigation for geological characteristics of Xifengshan gold deposit, the significant q6 gold-bearing quartz veinhas been selected to implement the primary halo geochemistry measure and abnormalities modeling. After testing and analyzing the 10 elements of q6 gold-bearing quartz vein, the results show that the strength of Au primary halo in earth surface is greater than that in drilling and trench. The Au primary halo of q6 in earth surface is extremely clear, which reaches the scale of primary halo in ore-body. And the horizontal zoning of Au primary halo in q6 quartz vein is basically symmetrical, indicating the northern tendency to incline of ore-body. In addition, the sequence of the horizontal zoning above also reveals that the main elements formed mines have mighty strength as well as large scale line. The research on element distribution and change regularity in this major auriferous quartz vein can provide mighty proof of ore-body chase as well as project design in this area.
