摘　　要：为解决危机矿山储量不足的问题,突破深部找矿瓶颈,对辽西排山楼金矿床深部的北东向矿体沿4条井下勘探线(0、6、12和16),从标高330米到175米7个开采中段采集271件样品,运用相关分析、R型聚类分析和因子分析的方法对每件样品20个微量元素进行了多元统计分析。结果表明,排山楼金矿床最佳前缘晕指示元素组合为As-Sb,近矿晕指示元素组合为Ag-Pb-As-Sb-Bi,矿上晕指示元素组合为Au±(Cu-Ag),尾晕指示元素组合为V-Mn-Co-Ti。通过对F1(尾晕)、F2(矿上晕)和F3(头晕)因子得分三维空间分布趋势图的研究,发现金矿体向南西深部侧伏,且延伸进入东西向矿带,表明东西向矿带深部也存在巨大找矿前景。在对已存两矿带正确划分的基础上,评价预测出第三矿带的存在,经勘探验证,预测矿带金矿石储量可观。271 samples were collected from the NE ore body of the Paishanlou gold deposit along four exploration lines （0, 6th, 12th and 16th） and seven different levels （300 - 175 m）. Twenty trace elements of these samples were analyzed through correlation, R-cluster and factor analyses. The results show that the best front halo indicator elements are As-Sb, near-ore halo indicator elements are Ag-Pb-As-Sb-Bi, ore halo indicator elements are Au＋（Cu-Ag） and rear halo indicator elements are V-Mn-Co-Ti. It can be seen from the 3-D distribution trends of F1, F2 and F3 that the orebody side-plungs to SW and there is a great prospecting in the depths of the EW orebody. Based on correct classification of the two known ore belt, the third ore belt was inferred and subsequent exploration confirmed this speculation.
