Other Abstract重点对盐井沟流域内泥石流堆积物及泥石流形成区土体的粘粒含量和粘土矿物进行了分析。分析结果表明,泥石流堆积物的粘粒含量与泥石流形成区土体的粘粒含量不匹配,前者仅为后者的1/14。粘土矿物主要为伊利石、绿泥石,次为蒙脱石,高岭石和蛭石。泥石流堆积物与泥石流形成区土体两者的主要粘土矿物种类基本相同。;  Yanjing Gully is located in Mianning County of Sichuan Province,at 102°14′-102°15′E, 28°15′-28°18′N. Since 1970,it has been a well-known debris flow gully at the northern section of Chengdu-Kunming Railway.The depoists in the watershed are earth body in the formation area, slag earth, debris flow deposits and muddy-water deposits in gully.This paper analyzed and determined the clay content of deposits and clay mineral characteristics (Table and Fig. 1).The average values of clay content:the earth body in the formation area is 19. 17%,slag earth 4. 57%,debris flow deposits 1. 41% and muddy-water deposits 1. 24%,in which the clay content of debris flow is less.The clay minerals in the area mainly are illite and chlorite, secondly are askanile and kao-line, etc.The distribution of clay minerals have the regional differences,i, e. I . In grainte area,clay minerals mainly are illite,secondly chlorite,and less askanile and kaoline etc. Ⅱ. In metamorphic rock area,they mainly are chlorite,seconly illite,and less askanile and kaoline. Ⅲ.In debris area, they are illite,secondly chlorite,less askanile and kaoline is almost no.
