Present-Day Kinematics of the Northern Margin of the Argun Continental Massif (Eastern Part of the Central Asian Belt)

Resumo

This paper reports the first data on present-day movements in the northern margin of the Argun Continental Massif, obtained on the basis of GPS measurements. The processed GPS data have been obtained to calculate the vector field of displacement velocities in the geodynamic survey site of the Upper Amur Region. The estimated displacement parameters (direction and magnitude) are indicative of the uniform velocity vector field of the points in the northern margin of the Argun Massif and the absence of considerable motions within its range (differences in the vector components do not exceed a few millimeters per year). A conclusion is made on the present-day kinematic integrity of the northern margin of the Argun Massif.
