| 摘 要： | 采用地质因子分析方法,对四川李伍预测工作区1∶20万水系沉积物39个元素化探数据进行了因子分析,得到9个因子,并从中找出反映地质构造和起主导成矿作用的少数因子,分别制成因子得分等值线图。该图直观地反演了成矿流体的运移演化过程。这表明该方法可作为第二轮找矿预测、地质填图等有效的化探手段。 |

| Abstract: | Factor analysis method is applied to study geochemical data for 39 elements in the Liwu ore district from 1：200 000 stream sediment geochemical survey. Contour diagrams for 9 factors are compiled, showing migration and evolution of ore fluids. The results indicate that factor analysis method may play an important role in metallogenetic prognosis and geological mapping. |
