地幔对流及其对岩石圈作用的研究进展

在地球动力学领域,地幔对流作为框架式的基本假说存在,许多的地质现象和动力学活动都由其解释和展开。从地幔对流理论的提出背景出发,分别从地幔对流的发展历程及研究现状、研究方法等多个方面进行详细回顾和论述。主要针对地幔对流对岩石圈的作用,从宏观板块运动和岩石圈应力场两个方面展开了客观的分析。目前,地幔对流的研究还处于基础研究阶段,还需结合多种研究手段更加深入探究其机理和影响。最后提出当前地幔流动研究存在的问题,并展望地幔对流未来研究的目标方向。

Progress of Mantle Convection and Its Lithosphere Effects Research

In the field of geodynamics, mantle convection exists as the basic hypothesis of the framework, from which many geological phenomena and dynamic activities are carried out. Starting from the background of the theory of mantle convection, this paper reviews and discusses in detail the development process, research status and research methods of mantle convection. The effects of mantle convection on the lithosphere are analyzed from two aspects: the macroscopic plate movement and lithosphere stress field. At present, the study of mantle convection is still in the basic research stage, and it is necessary to further explore its mechanism and influence by combining various research methods. At last, the problems in the study of mantle convection are pointed out and the future research direction of mantle convection is prospected.
