Abstract:

It is because different types of soft rocks have different erosion and weathering levels that the categorization of soft rock samples becomes important in the study of the erosion resistance of soft rocks.The paper implements the algorithms of fuzzy cluster analysis via Matlab and applied to the classification of the soft rocks in Inner Mongolia. The results show that the soft rocks in the study area can be categorized into nine types, namely purple sandstone with celadon mudstone interbeds，purple sandstone，purple sandstone interbedded with offwhite sandstone，purple sandstone with purple mudstone interbeds，offwhite sandstone with purple sandstone，offwhite sandstone，purple mudstone，offwhite sandstone with celadon sandstone and pink sandstone interbeds.

Key words: Fuzzy classifying analysis, Matlab, soft rocks, Inner Mongolia, sedimentology
