R 型聚类分析在区域化探元素分组中的作用探讨
Discussion on the affection of the R- cluster analysis applied in grouping elements in regional geochemical exploration
摘要
Abstract
R-type cluster analysis is a statistical method widely applied in processing geochemical data,whereas the deep research displays that the results of R-type cluster analysis can be really not effective positively in dividing element groups.In this paper,R-type cluster analysis of 39 elements in Permian stratum,Cretaceous stratum,biotite granite and the whole re-gion of Dashizhai area reveals that the divided elements combination can not clearly reflect the geological characteristics of the stratum,rock mass and the whole area,thus the application of R-type cluster analysis should be under caution.关键词
