摘要:
提要:以中国大陆的岩石圈岩石学结构模型和根据岩石圈动力学性质划分的克拉通型、造山带型、裂谷型、边缘海洋壳型和岛弧型5大岩石圈类型为基础,结合现今中国大陆西部挤压、东部拉张伸展的特点,提出以四川盆地、鄂尔多斯盆地和银川盆地西边界的岩石圈不连续为界,把中国大陆分为东部和西部2个一级构造单元;不同类型岩石圈为其二级构造单元,一些造山带型岩石圈的亚类为三级构造单元,并结合地质历史,简要讨论了其形成过程及其意义。
关键词:  岩石圈类型  岩石圈不连续  大地构造单元划分  中国大陆

Abstract:
Abstract:This paper proposes a new pattern of tectonic units of China based on the petrological structure model of the lithosphere under continental China and five types of lithosphere, namely, cratonic lithosphere, orogenic lithosphere, rift lithosphere, marginal-sea oceanic crust lithosphere and island arc lithosphere,distinguished according to the dynamic properties of the lithosphere, combined with the present characteristics of compression in the west and extension in the east of continental China. The content of the new pattern is as follows:the lithospheric discontinuity along the western boundaries of the Sichuan,Ordos and Yinchuan basins is used as the boundary to divide continental China into two first-order tectonic units, i.e. the western China tectonic unit and the eastern China tectonic unit;the above-mentioned different types of lithosphere are considered as their second-order tectonic units; and some subtypes of the orogen-type lithosphere are the third-order tectonic units. On the basis of the new pattern of tectonic units, combined with the geological history, their formation processes and implications for ore finding are also discussed briefly in this paper.
Key words:  type of lithosphere  lithospheric discontinuity  tectonic unit division  continental China
