六十年代以来,由于卫星重力测量和计算技术的迅速发展,有些研究者,如Runcorn(1967)和Liu(1976—1980),根据卫星重力数据计算获得地幔对流及其应力场图象来研究全球板块构造和区域构造。愈来愈多的事实表明,构造运动不仅是地壳和岩石圈层物质运动的表现,而更重要的是地幔物质运动的反映。因此,本文应用作者计算获得的岩石圈层下面地幔流运动图象与大地构造及近代构造运动的资料相对比,探索我国岩石圈层下的地幔对流格局形成及其对构造运动的影响。
Since the 1960s, some researchers, such as Runcorn (1967) and Liu (1976-1980), have studied the phenomena of mantle convection and its stress field based on satellite gravity data for the rapid development of satellite gravimetry and computational techniques Plate construction and regional construction. More and more facts show that tectonic movement is not only a manifestation of the movement of matter in the crust and lithosphere, but more important is the reflection of mantle material movement. Therefore, in this paper, we compare the mantle flow image below the lithosphere with the information of the tectonic and modern tectonic movements obtained by the author and explore the formation of the mantle convection pattern under the lithospheric layer and its influence on the tectonic movement.
