Such features are typical of ancient lower continental crust, e.g., Archean granulite terranes that experienced extensive U-Th loss and developed time-integrated low radiogenic Pb compositions. The occurrence of the west Ujimqin andesites indicates the existence of ancient continental lower crust beneath the NE China fold belt.4 The Mesozoic granitoids in the Zhangguangcai Range and Jiamusi block have lower Nd ε_(Nd =-3.5～+ 2.1, T_ = 1.0～1.27Ga and highly radiogenic Pb and Sr isotopic composition ~(206Pb/~(204)Pb = 18.4～18.9,~(87)Sr/~(86)Sr = 0.705～0.711, suggesting that the pelagic sediments of the Paleo-Asian Ocean or their metamorphosed derivates were an important component in the region.5 The Pb isotope mapping results show that the mafic rocks in the northern Hinggan Mountains have higher and weakly variable ~(206)Pb/~(204)Pb ratios than those from the southern Hinggan Mountains and the Liaoyuan-Yanji area.

该套岩石的出现为证明东北地区存在古老大陆下地壳提供了重要证据。4张广才岭-佳木斯地区中生代花岗岩表现出低ε_(-3.5～+2.1)、高T_(1.0～1.27Ga)和高放射成因Sr~(87Sr/~(86)Sr=0.705～0.711和Pb同位素组成~(206Pb/~(204)Pb=18.4～18.9，反映了古亚洲洋远洋沉积物或变沉积岩为区域地壳的重要组分之一。5同位素填图结果表明，大兴安岭北区基性火山岩表现出较高且变化小的~(206)Pb/~(204)Pb比值；而南兴安岭-辽源-延吉地区中生代基性火山岩整体上表现出相对北区低~(206)Pb/~(204)Pb同位素比值特征。

They are:①completed total 8 000 km long natural seismic profiles cross the northern boundary and central part of the plateau, identified several deep-cut lithospheric faults and low velocity and low density bodies under the central part of the plateau related to Cenozoic volcanic eruption, the Tarim block subducted beneath the Altun Mts;②found the evidence that the Altyn Tagh fault formed in 220～240 Ma and at least 400 km sinistral offset since, and determined quantitatively deformation in Cenozoic;③discovered 350 km long high-ultrahigh pressure metamorphic belt in the south border of the Qilian terrane,which brobably represented the Early Paleozoic boundary between the North China and Yangtze plates;④according to new discoveries of caledonian ophiolite,granite are subducted complex established paleo-collision orogenic framework of northern Qinghai-Tibet plateau;⑤proposed a new model .

本文展示了中法1995～2000年青藏高原北部地学研究的如下主要新进展：①完成8 000 km长的青藏高原北部及中部天然地震岩石圈探测剖面，确定若干条岩石圈断裂，发现与新生代火山喷发有关的青藏高原中部深处的低速、低密度体，塔里木地块俯冲于阿尔金山之下；②提出阿尔金断裂形成于220～240 Ma和左行平移400 km的科学依据及确定其新生代变形量；③确定祁连南缘350 km长的高压-超高压变质带，提出其可能代表早古生代时期北中国板块与扬子板块之间西部界限的新认识；④根据加里东期蛇绿岩、花岗岩及俯冲杂岩带的新发现，初步建立了古碰撞造山格架；⑤提出高原隆升的&地幔底辟和内向陆内俯冲&的新假设。

北极作为全球天气变化的驱动器和调节器，对全球的天气变化非常敏感，通过对北极海域古海洋学的研究，将有助于我们猜测未来的全球天气演变趋势。

BILL STOUT: I see paleo-artists as conduits to the public on behalf of the scientists.

比尔·斯道特：我觉得古生物艺术家是一个通向公众的渠道，他们代表着科学家。

This suggests that subduction of a paleo-ocean basin occurred between the Paleoproterozoic North China craton and Qaidam craton.
