中文摘要：

在北方中国 Craton ( NCC )的东方部分基于早白垩纪 Feixian 高镁的暗岩的水内容的研究，东方 NCC 的早白垩纪 lithospheric 披风是高度含水的，这被建议了(> 1,000 ppm ， H2O wt )并且这个高水位线内容显著地减少了 lithospheric 披风的粘性并且为 NCC 的破坏提供了一个前提。向北， NCC 的东方部分从南方经历了海洋的盘子的多级式的 subduction，东方后来站在一起早古生代，并且这些事件可能引起了 NCC lithospheric 披风的强壮的水和。决定哪个 subduction 最作出贡献到这水和，我们测量了 Fushan 的早白垩纪高镁的闪长岩在 Taihang 山的南方中央的部分招待的橄榄岩捕虏体的水内容。我们的结果证明在 Taihang 山的南方部分下面的早白垩纪 lithospheric 披风的水内容是 ~ 40 ppm 并且比在 NCC 的东方部分下面的当代的 lithospheric 披风的显著地低。因此， NCC 的东方部分的早白垩纪 lithospheric 披风的水和能从西方方面被归功于到和平的板的 subduction。因此，在 NCC 的破坏的主要动态因素是可能的和平的板的 subduction。

英文摘要：

Based on studies of the water content of the early Cretaceous Feixian high-magnesium basalts in the eastern part of the North China Craton （NCC）, it has been suggested that the early Cretaceous lithospheric mantle of the eastern NCC was highly hydrous （〉1,000 ppm, HeO wt.） and that this high water content had significantly reduced the vis- cosity of the lithospheric mantle and provided a prerequisite for the destruction of the NCC. The eastern part of the NCC had undergone multistage subduction of oceanic plates from the south, north, and east sides since the early Paleozoic, and these events may have caused the strong hydration of the NCC lithospheric mantle. To determine which subduction had contributed most to this hydration, we measured the water contents of the peridotite xenoliths hosted by the early Cretaceous high-magnesium diorites of Fushan in the south- central part of the Taihang Mountains. Our results demon- strate that the water content of the early Cretaceous litho- spheric mantle beneath the south part of the Taihang Mountains was ~ 40 ppm and significantly lower than that of the contemporary lithospheric mantle beneath the eastern part of the NCC. Thus, the hydration of the early Cretaceous lithospheric mantle of the eastern part of the NCC can be ascribed to the subduction of the Pacific plate from the west side. Thus, the main dynamic factor in the destruction of the NCC was likely the subduction of the Pacific plate.
