神农架地区第四纪冰川遗迹与冰期划分

QUATERNARY GLACIATION IN SHENNONGJIA

神农架是中国第四纪地质环境演变的热点地区之一。本文通过对第四纪冰川地貌、冰碛残迹及二者关系研究，提供了本区第四纪古冰川发育的多方面证据。神农架地区在第四纪时期曾发生三期冰期和两期冰缘期，即松柏冰期、木鱼坪冰期、龙潭冰期、松香坪冰缘期、神农架冰缘期。

Shennongjia located in central China is an important area to study Quaternary geology.Based on the distribution of glacial vestiges,we make a discussion of the Shennongjia Quaternary glaciation.There are three glacial substages,i.e.Songbai glaciation,Muyu glaciation,Longtan glaciation,and two epiglacidtions,i.e.Songxiangping epiglaciation,Shennongjia epiglaciation.A study of the Shennongjia Quaternary glaciation provides new data for solution of the dispute over the Quaternary glaciation in eastern China. Quaternary climatic stratigraphic sequence in Shennongjia is established for the first time.
