| 摘 要： | 根据金山金矿化区20 km2土壤地球化学测量结果,运用聚类分析和因子分析,显示Au与Ag、As、Sb相关性较好,可作为金矿找矿间接指示元素;并通过计算各元素背景值及异常下限,圈定出9处金异常和其他元素异常35处。区内主要发育含硫化物蚀变岩型和含硫化物石英脉型金矿体。其中北西向断裂控制矿体走向,为重要的控矿构造。综合地质条件及元素异常特征,预测并圈定出3个Ⅰ级靶区和2个Ⅱ级靶区,并在Ⅰ级靶区经地表槽探工程验证,发现并控制14条矿体。

| Abstract: | According to the soil geochemical survey result of 20 km2 range in Jinshan mineralization zone,using cluster and factor analyses,the authors concluded that Au has better positive relevance with Ag,As and Sb than other elements.These elements can be as the good indicators for gold mineralization prospecting.By measuring the background value and anomaly threshold of each element,there are 9 anomalies of Au and 35 anomalies of other elements delineated.The gold ore bodies in sulfurous altered rock type and quartz vein type are mainly developed within the zone.North-west fracture is the most important ore-controlling structure.Integrating the geological conditions with the abnormal characteristics of elements,we extracted three prospecting targets with Ⅰ level and two target sections with Ⅱ level,and with the surface trenching engineering work in Ⅰ level target sections,14 ore bodies were delineated. |
