Abstract:This paper studies the building method and achievements of the global plate boundary model NNR-MORVEL56, and the differences between it and NNR-NUVEL1A, with respect to the plate relative angular rate and root-mean-square of the rate (RMS). It then discusses the influence in angular rate of the 31 small plates from PB2002 on the other 25 major plates. Mean while, based on the NNR- MORVEL56 boundary, the paper establishes the measurement model by using the latest and most comprehensive global space geodesy measurement data, and it analyzes the correlation with NNR-MORVEL56 to test the rationality of the plate division of the model MORVEL56. Aiming at the complicated characteristics of geological structure in China, this paper puts forward some advice referring to the NNR-MORVEL56 boundary dividing method.
