| Abstract: | The Dun-Mi faulted zone ia an important active faulted zone in Jilin province. For evoluating crustal stability of the Dunhua region, we made a research on the formation age and active mechanical property of the Erdaodianzi-Dazuizi section. By comprehensivly studying on the data of volcanos,seism and geochemical exploration,and determination of fault gouge thermoluminescence age and faulted gas,it is considered that the latest active age should be 100 000 years ago,therfore,the region of Dunhua City should be a stable (unactivity) area. |
