摘要:
通过野外考察和室内样品分析,对青藏高原东部边缘陇南地区第四纪泥石流沉积物及发育历史进行了研究,认为陇南地区第四纪泥石流活动主要集中在2.0～1.5MaB.P.、0.7～0.6MaB.P.、0.5MaB.P.、0.11～0.08MaB.P.、0.05～0.02MaB.P.以及全新世的几个阶段.泥石流活动受控于青藏高原隆起高度及区域气候环境演化,泥石流沉积物的化学成分及孢粉记录了该区第四纪不同时段的环境特征..
Abstract:
By the field survey and the analysis of indoor samples,the authors made a study of the Quaternary debris flow sediments and the formation history in Longnan area of the eastern fringe of Tibetan Plateau,and thinks that the Quaternary debris flow’s activities in Longnan are amainly concentrate on 2.0～1.5 MaB.P.,0.7～0.6 MaB.P.,0.5 MaB.P.,0.11～0.08 MaB.P.,0.05～0.02 MaB.P.,and Holocene Epoch respectively.Debris flow’s activities are controlled by the height of the uplift of Tibetan Plateau and regional climate environment.The chemical compositions of debris flow sediment and the spores record the environmental features in the different stages of the Quaternary period in this area.
