敦化—密山断裂带(二道甸子—大山嘴子段)断裂活动性评价
|
摘要
敦密断裂带是发育历史长、活动期次多的区域性大断裂，其形成时代及不同时代的活动力学性质不同。为评价敦化市及周围地区的区域地壳稳定性，借助于断层泥热释光测定、断裂气测量及地震、火山资料对断裂带的不同部位做出了稳定和相对稳定的定量结论。
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.
