摘要
The Amurian Plate was proposed by Zonenshain as a microplate within the Northeast Asia.Many issues concerning the Amurian Plate,such as whether the Amurian Plate exists,where its southern boundary is,are presently highly debated.Although many scholars employed the evidence of geology and geophysics to conduct research on the possibility about the existence of Amuria.Nevertheless,complicated tectonic characteristics as well as seldom and dispersed seismic activities make the issue of Amurian plate a problem full of disputation.With the improvement of Global Positioning System(GPS),the GPS observations can provide high-precision,large-scale,quasi real-time and quantitative data of crust movement,and make obtaining large-scale velocity field of crust movement in a short time possible.In this paper,based on the new GPS data and statistics tests,we conducted significance tests to investigate whether Amuria is a part of the Eurasia(EU) or a separate block which is independent from EU and to define the ambiguous southern boundary of the Amuria.
