| 中文摘要: |
| 采集溧水观山铜矿5个钻孔Cu、Pb、Zn、Au、Ag、W、Mo、As、Sb、Sr等10种元素应用SPSS软件进行钻孔原生晕特征分析,为深部成矿预测提供理论依据。结果显示As、Sb、Ag可作为矿体前缘晕指示元素,Au、Cu、Pb、Zn 可作为矿体近矿指示元素, W、Mo可作为矿体尾晕指示元素。聚类分析及因子分析显示成矿的多期性、叠加性。原生晕垂向分带显示深部存在第二个铜含量峰值,可能存在隐伏铜矿化带。 |
| 英文摘要: |
| elements including Cu, Pb and Zn etc. are collected in 5 boreholes of Guanshan copper mine in Lishui and have been analyzed by SPSS software to provide theoretical basis for deep metallogenic prognosis. The conclusion shows that the elements As, Sb and Ag can be used as indicator elements for the frontal halos of ore bodies and Au, Cu, Pb, Zn can be used as indicator elements of near orebodies, and W and Mo can be used as indicator elements of ore body tail halos. Cluster analysis and factor analysis show that the mineralization is multi-phase and superimposed. The vertical zoning of the primary halo indicates that there are second copper peaks in the deep layer, and there may be a concealed copper mineralization belt. |
