云南玉溪东风水库断裂的第四纪活动

Quaternary Movement of Dongfeng Reservoir Fault in Yuxi,Yunnan

在野外地震地质调查的基础上,根据东风水库断裂在第四纪地质和地形地貌上的表现,并结合测年手段,综合分析和研究了该断裂的第四纪活动,包括时代、性质和速率,发现组成该断裂的各分支之间其第四纪活动存在显著的差异。

Based on the field investigation and the fault＇s representation in Quaternary geology, landform and relief, the Quaternary movement （ age, character and rate） of the Dongfeng reservoir fault in Yuxi, Yunnan, was studied. It is found that the Quaternary movement of every branch of the fault is obviously different.
