科普新闻：中国是世界中央的地学理论
|
2015年9月21日，Nature Communications发表了中（四位）、英（一位）两国科学家的古元古代地学理论，认为中国的确是古代地球板块的中央。应该祝贺中国科学院地质与地球物理研究所的成就。
去找英文谷歌，没有这则新闻，雅虎只有原文的条目，没有其他科普媒介发布。只有中国的报章有这段新闻的科普报导。原文十页，比一般简讯长，比较难懂，主题结论不明显。这则新闻与地球大陆起源，生物起源，人类起源有关，应该全世界的人都会感兴趣，可西方媒体没有科普报导，没兴趣，还是不懂？

Paleoproterozoichigh-pressure metamorphism in the northern North China Craton and implicationsfor the Nuna supercontinent.
The connection between the North China Craton (NCC) and contiguous cratons is important for the configuration of the Nuna supercontinent. Here we document a new Paleoproterozoic high-pressure (HP)complex dominated by garnet websterite on the northern margin of the NCC. The peak metamorphism of the garnet websterite was after B1.90 Ga when it was subducted to eclogite facies at B2.4 GPa, then exhumed back to granulite faciesat B0.9 GPa before B1.82 Ga. The rock associations with their structural relationships and geochemical affinities are comparable to those of supra-subduction zone ophiolites, and supported by subduction-related signatures of gabbros and basalts. We propose that a B1.90 Ga oceanic fragment was subducted and exhumed into an accretionary complex along the northern margin of the NCC. Presence of the coeval Sharyzhalgai complex with comparable HP garnet websterites in the southern Siberian active margin favoursjuxtaposition against the NCC in the Paleoproterozoic.
