| 摘 要： | 文章对青海省达肯达坂山地区1∶5万水系沉积物测量所得数据进行R型因子分析,提取了5种具有代表性的因子组合类型,对各因子元素组合得分归类,绘制了测区地球化学分区图。通过判读分析,地球化学分区图反映了不同地质体中以相应元素组合类型为主的地球化学异常。研究对比组合分区与因子得分异常,有利于推断相关元素的浓集部位,也为确定找矿靶区提供了方向。

| Abstract: | According to R type factor analysis of data from stream sediment survey at scale 1 ∶ 50000 in Dakendaban area 5 kinds of representative factors are extracted.Scores of element association for each factor are classified and the geochemical division map of the survey area is drawn.The map shows the corresponding element association anomlies the geological bodies.Comparison study of association division and score anomly is favorable to predict the concentration center and provides evidence for locating the prospecting targets. |
