地球化学原生晕在玲珑金矿中的应用——以47号矿体为例

Application of Geochemical Primary Halo in the Linglong Gold Mine——the No.47 Orebody for Example

玲珑金矿位于山东省招远市与周边县城的交界处,是我国最重要的一种金矿类型。在所得样品的测试数据的基础上,对Au、Ag、As、Bi、Co、Cu、Hg、Mn、Mo、Ni、Pb、Sb、Th、U、V、Zn 16种元素进行了分析,并绘制相应元素相关图件。最终结合矿体原生晕分带序列,研究了该金矿床的元素相关性特征和地球化学参数变化规律。其中,元素相关性特征包括:Au、Ag、As、Bi、Cu、Co、Pb、Mo是金矿的最佳指示元素;Hg、Mn、Ni、V、Zn等与Au元素有一定的相关性;Sb、Th、U与Au相关性不大,无明显的指示意义。经过计算,得出47号矿体的原生晕分带序列自上而下分别为As、Pb、Ag、Cu、Hg、Sb、M、Ni、T、V、U、Mn、Zn、Bi、Co、Au。其中,近矿元素Au、Ag、Bi、Pb、Zn中的大多数出现在序列的尾部,这一反常的特征,在一定程度上可以预测在深部有隐伏矿体的存在。

The Linglong gold mine is located at the junction of the city of zhaoyuan city in shandong province, is the most important type of gold mine in China. The paper is based on the test data of the sample. Through analysis of 16 elements such As Au, Ag, As, Bi, Co, Cu, Hg, Mn, Mo, Ni, Pb, Sb, Th, U, V, Zn, etc, and draw elements related to the elements. In the end, the correlation characteristics of the gold deposits and the changes of geochemical parameters were studied. Au, Ag, As, Bi, Cu, Co, Pb, Mo are the best indicators of gold mine. Hg, Mn, Ni, V, Zn have some correlation with Au elements. Sb, Th, U are not correlated to Au. After calculation, the original halos sequence of the 47 ore body were respectively from top to bottom： As, Pb, Ag, Cu, Hg, Sb, M, Ni, T, V, U, Mn, Zn, Bi, Co, Au. Most mineral elements Au, Ag, Bi, Pb, Zn appear at the end of the sequence, this anomalous feature can be predicted to some extent with the existence of hidden ore bodies in the deep.
