摘要:
在自然界中,泥石流形成环境、发育规律、空间分布等特征的演化和分异,导致了不同时期、不同区域、不同沉积过程和不同沉积地貌部位泥石流沉积亚相组合的变异.该文拟在作者所建泥石流沉积模式基础上,以蒋家沟为例进一步讨论泥石流亚相的组合及变异规律.此外,初步探讨了夷平面解体后,泥石流沉积在地貌回春不同阶段的发育规律.
Abstract:
In the nature,due to the debris flow developing under different environment and depositing various landform,it led to combination variation of depositional sub facies on the different period,various regions and different depositional landform.On the basis of depositional model of debris flow built by author,the combination and variation of depositional sub facies of debris flow on the Jiangjiagou valley,Yunnan Province,was discussed.The main features of debris flow of Jiangjiagou are as follows:(1)the erosion layer(C) very developed;(2)the layer(B) of surface mud didn’t run in succession;(3)the thickness of debris layer(A) is thin;(4)the layer(D) of floor mud developed weakly.The main combination of sub facies is C-A-C and B-A-C.
