山东黄埠岭金矿床主要工业矿体指示元素研究

Study on the indicator element of main economic orebody in Huangbuling gold deposit,Shandong province

地球化学元素分布规律的研究是揭示元素矿化富集及空间变化规律的重要途径之一,查明指示元素的含量及其空间分布特征,对于评价矿床深边部含矿性具有指导意义。本文运用统计及克里格插值方法查明黄埠岭金矿成矿指示元素的分布特征,认为矿脉中除N i和Hg以外其余9个元素的均值明显高于克拉克值,元素的分散富集作用强烈,元素的垂向分带特征明显,可作为矿床深部含矿性评价的依据。

Study on the distribution of geochemistry elements is one of route to show up mineralization enrichment of elements and spatial compositional variation. Study on the elements content and spatial distribution characteristics of elements are very important to revealing ore potentiality evaluation in depth of gold deposit. The paper discusses spatial distribution characteristics of metallogenic elements in the Huangbuling gold deposit by using statistics and Kriging method. It is considered that the rest of nine elements average hyper - kriging clearly, excluding elements Ni and Hg in vein, and the more effects of the dispersal or enrichment of elements are intense, the more characteristics of vertical zonality are evident. The conclusion is important for ore evaluation in depth of gold.
