| 摘 要： | 完达山地区位于中国东北地区东部,主要由一套近南北走向的玄武岩、堆晶岩、(超)基性熔岩、硅质岩和泥质岩组成,为中国东部唯一的中生代海相地层发育区,出露有太平洋板块俯冲形成的增生杂岩组合。研究区矿产资源丰富,已发现中型矿床1处,小型矿床4处,找矿前景较好。在全区1∶20万水系沉积物测量基础上,对完达山地区16种成矿元素进行相关性分析、聚类分析、因子分析、单元素异常分析和组合异常分析。分析结果表明,Au、Ni、Cr、Bi、Hg异常高值点多、离散性强,地质及地球化学条件优越,成矿潜力强。Au成矿作用主要与中酸性岩浆岩相关,Ni、Cr成矿作用主要与(超)基性岩浆熔离作用相关。在此基础上,结合区内地质、构造、物探和已知矿床(点)等信息,优选出4处成矿远景区,即258高地金成矿远景区、八里桥—仙人台铜镍钨锡成矿远景区、四平山—358高地金银成矿远景区和跃进山—先锋北山金银铜铁成矿远景区,为完达山地区整体找矿工作部署和区域成矿规律研究提供科学依据。

| Abstract: | Located in the eastern part of Northeast China, the Wandashan area mainly consists of basalts, cumulates, (ultra)basic lavas, silicalite and pelites. It contains the only succession of Mesozoic marine facies sedimentary strata in eastern China, known as the Hyperplasia Complex. Mineral resources are rich, and 1 medium-sized deposit and 4 small deposits have been discovered in this area. In addition, it shows more ore potential. Based on the 1:200000 geochemical data of stream sediments in Wandashan area, the authors carried out the correlation analysis, cluster analysis, factor analysis, single element anomaly analysis and combination analysis of 16 kinds of ore-forming elements. The analytical results show that Au, Ni, Cr, Bi, Hg have lots of high points, strong discreteness, favorable geological and geochemical conditions, and strong metallogenic potential. Au mineralization is mainly related to acidic magmatic rocks, and Ni, Cr mineralization is related to the (ultra)basic magma liquation. Combined with geology, tectonics, geophysical exploration and ore deposits (ore spots), the authors selected four metallogenic prospective areas:258 highland gold metallogenic prospective area, Baliqiao -Xianrentai copper -nickel -tungsten -tin metallogenic prospective area, Sipingshan-358 highland gold-silver metallogenic prospective area, and Yuejinshan-Xianfengbeishan gold-silver-copper-iron metallogenic prospect area. These metallogenic prospective areas provide the scientific basis for the deployment of ore-prospecting work and the study of regional metallogenic regularity of the Wandashan area. |
