新疆北天山地区盆山交界主要构造带运动特性研究
The study on movement performance of the major structural belt mountain basin border in North Tianshan in Xinjiang region
摘要
Abstract
Using GPS velocity field data of 2009 ~2013 period,based on model of the block motion and GPS section,we studied the movement performance of the major structural belt mountain basin border in North Tianshan in Xinjiang region.Results show that the block of the uniform strain model can better describe the Tianshan block integral movement characteristics;Rigid body rotation model can better describe the overall movement charac-teristics of the Junggar block;Strike-slipping rate of the southern margin fault of Junggar block,the northern margin fault of Bogdais less than 1 mm/a,extrusion compression rate is 3~4 mm/a;the northern margin fault of Bogda remains a feature of strain accumulation in certain degree.关键词
