| 摘 要： | 本文通过对山东乳山金矿床Ⅱ号主矿体参加储量计算的34个钻孔和三个中段的278个样品的金品位进引了统计分析,探讨了金品位的空间分布特征与成矿作用的联系和特高品位的处理问题.据分析统计的结果,显示出该矿体具有对数正态分布和双峰频率分布的特征.因此,可以推断该矿床为两期以上矿化叠加的结果.为了消除储量计算中金品位非正态分布的影响.作者亦提出了对特高品位的处理方案.

| Abstract: | This paper presents the statistical analysis of gold grade of Jin Qingding gold deposit. Relation between gold grade distribution and metallogeny is revealed and the author proposes a subject, ie. how to deal with the extreme high grade data. The statistical data exhibits a Log-normal distribution of gold grade and distribution frequency with two peaks suggesting two stages of mineralization of the deposit. |
