大兴安岭嫩江科洛浅覆盖区断裂构造调查
摘要
Abstract
The Keluo area of Nenjiang County, which is situated in the Nenjiang River basin on the eastern slope of northern Da Hinggan Mountains,is a typical shallowly covered area.In this paper,the authors tried to recognize fault structures and analyze their stress mechanism in the area through synthetic techniques of interpretation and deduction on gravity and aeromagnetic data combined with field outcrop survey.Based on verification of the fault structure in the exposed bedrock area,the authors hold that this synthetic method has good effect in acquiring the mechanical properties and activity characteristics of the faults under the shallowly covered ar-ea.It is therefore suggested that the synthetic application of gravity-magnetic and outcrop investigation could be mutually corroborat-ed and, with this means, the multi-solution could be reduced, and the reliability of interpretation could be improved. In addition, such a synthetic application can provide an effective technique support for the geological mapping,regional tectonic study and metal-logenic prediction in the shallowly covered area.关键词
