| 摘 要： | 应用有关多元统计分析方法来研究地层,进行化学地层划分的探讨、岩层分析等,为合理正确划分地层提供有效的定量依据,探讨有关方法的实用价值,丰富化学地层学的研究内容。结合实践,对一条实测地层剖面进行了较详细的分析研究,并与野外实际地质情况加以对比解释,从而揭示出更多的地质信息、规律,对地层有了更多的认识。

| Abstract: | We employed several different multivariate statistical methods to subdivide strata on the base geochemical data.These methods include optimization,Q cluster analysis,and two-group discriminant analysis.We find that the results match well with the geological records and contribute to our understanding of the geological entity of the studied strata. |
