摘要
本文应用因子分析对新疆达木斯石炭系剖面岩石样品的化学分析数据进行研究,根据 R 型因子分析的结果,探讨岩石化学组分的共生组合关系,找出本区石炭系岩石化学组分中的典型变量。运用 Q 型因子分析划分出不同的岩石类型,为地层和沉积相的划分提供了解释依据。
Chemical whole analysis data of carboniferous rock samples of Xinjiang Damusi Sac- tion have been studied with application of factor analysis in this paper.According to the result of R-mode factor analysis,the coextensive assemblage relation of the rock chemical components has been discussed and the typical variation in the rock chemical components of carbonifeious has been found out.Different rock types can be classified based on Q-mode factor analysis, which offers the interpretative basis for the stratigraphy and sedimentary facies of the section.
