| 摘 要： | 长期以来,国内外皆在区别混杂堆积物的成因问题上遇到过困难。本文主要探讨粘性泥石流和稀性泥石流(水石流)的沉积类型与特征问题,并适当地指出了它的某些沉积类型与冰碛物易混淆之处。一、泥石流堆积的构造特征沉积构造划分有两类:一、在堆积作用的同时直接由沉积介质活动所形成,能生动.

| Abstract: | In this paper, such terrigenous elastic deposit, which has a large disparity in gram size with no sorting or a little sorting, and coarse elastic particles scattered in fine filling matrixes, 0r fine particles filled amoag interstice of coarse clastics, is defined as diamicton or diamictite.Debris flow deposit is one of the diamictons. Over a long time, it has encountered a lot of difficulties to distinguish the genesis of diamicton at home and abroad. |
