Abstract

The quantitative processing of gravimetric data is performed and the 3D density model is calculated for the southern part of the Russian margin of Eurasian continent. Based on the density model, new patterns of disjunctive tectonics at different depth levels are revealed and the position of the region at the global tectonic level is shown. It is established that the transition zone is an integrated lithospheric structure of the northeastern orientation, in which there are mantle blocks with the boundaries corresponding to the borders of depressions and major tectonic objects. The data obtained may be applied for refinement of the deep structure and paleogeodynamics of the studied area.

俄罗斯远东南部大陆-海洋过渡带岩石圈的结构：来自密度模拟的证据

摘要

对重量数据进行定量处理，并为欧亚大陆俄罗斯边缘的南部计算3D密度模型。基于密度模型，揭示了不同深度水平的分离构造的新模式，并显示了该区域在全球构造水平上的位置。已经确定过渡带是东北方向的整体岩石圈结构，其中有地幔块，其边界对应于凹陷和主要构造物体的边界。获得的数据可以用于研究区域的深部构造和古动力学。
