Amurian板块旋转模型及其沿郯庐断裂带二级划分
Amurian Plate Rotation Model and Its Secondary Division along the Tanlu Fault Zone
摘要
Abstract
The Amurian plate(AM)in the northeast Asia plays a particularly important role in the estimation of surrounding crustal movements and interpretation of seismic activities, especially which can interpret the role of Tanlu fault in plate tectonic.However, due to the lack of research data, the location of the southern border is still controversial, therefore,the Tanlu fault zone will be the key to further defining the Amurian plate. Based on the analysis of the focal mechanism solutions and stress vector direction of the Baikal rift zone stretching belt and Sitanuowoyi mountains extrusion belt, combining with GPS data in northeast China, the paper establishes the main rotation model of Amurian plate whose center is located in near E118.4℃±2.4℃, N57.5℃±1.2℃. By using the x2method, the paper calculates the correlation of the Korean Peninsula between the main Amurian plate and China Southern block, and finds that the Korean Peninsula does not belong to the Amurian or Chinese Southern, which is a relatively independent rigid block. The magnitude of the energy release also shows that the same problem. The conclusion shows that the Tanlu fault zone should be the southern boundary of the Amurian plate, at least a secondary division boundary zone of the Amurian plate.关键词
