| 摘 要： | R型因子分析中，因子计量从所有原始变量中将某一特定因子的有关信息集中起来，可被用来解释某一特定地质作用形成的样品在不同空间的分布等问题，由已知典型地质体的元素含量等地球化学指标计算出来的因子计量系数矩阵作为模型，用这个模型可以计算未知地质体的因子计量，这种方法，不仅可以节省每次加入新样品或舍去部分样品时所有因子计量图都需要重新做的繁重的工作量，而且更重要的是这种图的地球化学意义明确，使我们能够用已知的典型地质现象去预测未知地质观象提供了一条新的途径。

| Abstract: | In the R-mode factor analysis, factor score is resulted from a special factor that has concentrated the most significant information about all the relevant original variances. The factor then can be used to explain the special distribution of samples that are formed at certain geological process. Factor score matrix is calculated from the geochemical indexes that involve the element concentrations of a well-studied typical geological body, which is the so-called known mode. Factor scores of unknown geological body can be calculated with this mode. Compared with the conventional procedure, this method possesses the following advantages. It is much easier to calculate because the mode makes it unnecessary to repeat all the maps of factor score when adding new samples. And more, the mode provides very simple and clear meaning of geochemistry. At last, it gives us a new method in which we can predict unknown geological phenomenon with known typical geological phenomenon. |
