| 摘 要： | 利用R型因子分析方法对胶东半岛乳山寨幅1∶5万水系沉积物测量数据进行了分析,提取出7个具有代表性的因子,绘制出地球化学分区图,并讨论了各分区的地质地球化学特征;将研究区内水系沉积物样本所体现的全部地球化学统计信息在一幅图中以区块的形式得以反映,通过对其判读分析各类分区特定的地质地球化学特征,同时结合圈定的综合异常,进一步缩小了找矿靶区,可为矿产勘查工作指明方向。

| Abstract: | In this study R-factor analysis is used to deal with stream sediment data of Rushanzhai sheet, Jiaodong Penisula. Seven representative factors are extracted and geochemical zoning chart drawn. Geochemical characteristics of each zone are discussed. All geochemical statistical information embodied by the sediments specimen of the study area in blocks is reflected in one map. Interpretation and analysis of specific geological and geochemical characteristics of each zone are combined with the integrated anomlies oulined to narrow target area point out the direction for the next prospecting work in the area. |
