岩石圈规划是继地球动力学规划之后的又一国际性多学科合作研究项目。它的重点是研究大陆岩石圈的性质、动力、起源及其演化。规划发起人认为,对于大洋盆地的认识虽然还很不够,但由于板块构造理论对大洋盆地的应用比较成功,所以可以把研究重点转移到大陆及其边缘上来。大陆岩石圈由于平均密度低,始终向下突出于地幔之中,所以能比大洋岩石圈生 Lithosphere planning is another international multidisciplinary cooperative research project following the Earth’s dynamics planning. Its focus is on the study of the nature, motivation, origin and evolution of continental lithosphere. According to plan sponsors, although understanding of the oceanic basin is not enough, the application of plate tectonics to the oceanic basin has been relatively successful. Therefore, the research can be shifted to the mainland and its periphery. Due to its low average density, the continental lithosphere always protrudes downward into the mantle so that it can outgrow the oceanic lithosphere
