- Abstract:
-
In order to study the characteristics of tectonic movement in Heilongjiang section of the Yilan-Yitong fault zone,we calculated the recent three-dimensional velocity field based on GPS continuous station and geological data in Heilongjiang region from 2016 to 2019,and inverted the fault slip rate by constracting the fault model.The following conclusions are obtained:the Heilongjiang section of the Yilan-Yitong fault zone generally shows a subsidence trend,with a settlement rate of 1~2 mm/a.The fault is dextral strike slip,and the strike slip rate is(1.7 ± 0.4)mm /a at 15 km below the locking layer.The Yilan-Yitong fault zone is divided into Jiamusi-Luobei segment and Wuchang-Jiamusi segment.The activity of the Jiamusi-Luobei segment is mainly tension,and the dextral strike slip is a supplement,that of the Wuchang-Jiamusi segment is mainly dextral strike slip,and the tension is a supplement.
