摘要
岩石圈不连续是岩石圈块体间的构造薄弱带,也是岩石圈单元和深部成矿单元划分的重要界线;本文以华北地台为例,阐述岩石圈不连续的概念,初步探讨了岩石圈不连续在大陆成矿作用过程中的作用,并讨论了岩石圈不连续的识别标志。
Lithospheric discontinuities are tectonic weak belts between the lithospheric blocks, and also serve as important borderlines for the division of lithospheric units and deep metallogenic units. This paper has expounded the concept of lithospheric discontinuities with North China platform as an example, probed into the roles of the lithospheric discontinuities in the process of continental metallogenesis, and discussed the identifying criteria of lithospheric discontinuities.
