Profile No.1,located at Xiao-dang-yang-qiao of Shen-nong-jia re-gion,1010 meters above sea level,has its characteristes like those of theyellow brown soil,main clay mineral vermiculite,Illite and Chlorite.Profile No.2 and No.3,located at Ti-chang-he with an elevationof 1500 meteres and Hong-ping with an elevation of 1830 meters respec-tively,have their characteristics like those of the yellow soil,mainclay minerals Illite and chlorite.Profile No.4,located at Tian-meng-ya with an elevation of 2200meters,has its characteristics like those of the dark brown soil,mainclay minerals Lllite and chlorite.Based on those mentioned above,it can be concluded that lower di-stributions of the yellow brown soil,the brown soil and the dark brownsoil migth not be over 1000,1500,2200 meters respectively in the south-eastern part of Shen-nong-jia region.
