| 摘 要： | 约1 000~820 Ma的新元古代青白口纪早期，全球罗迪尼亚超大陆汇聚的构造环境是中国该时期洋陆分布的主控因素；华北、扬子和塔里木三大陆块均位于当时地球的北半球，三大陆块的外围被边缘海和洋环绕.华北陆块周缘以稳定型的滨浅海沉积为主；而扬子陆块周缘表现为沟-弧-盆体系；塔里木西北缘发育阿克苏活动陆缘，塔里木北东缘和西南缘分别发育库鲁克塔格被动陆缘浅海碎屑岩建造和铁克里克被动陆缘碳酸盐岩建造.环绕华北、扬子和塔里木三大陆块的边缘海和洋内分布有众多裂离地块，多数地块亲扬子和塔里木陆块，如伊宁、敦煌、阿拉善、松潘、罗霄和武夷等；少数亲华北和西伯利亚陆块，如宝音图、锡林浩特、额尔古纳、韩家园、佳木斯和阿勒泰等.

Oceanic and Continental Blocks Distribution during Neoproterozoic Early Qingbaikouan Period (1 000-820 Ma) in China |
| |
| Abstract: | During Early Qingbaikouan Period, Neoproterozoic (1 000-820 Ma), the structural background of global assembly of the Rodinia supercontinent is the key factor on the pattern of ocean and block in China. The three big blocks, North China, Tarim and Yangtze, located in the Northern Hemisphere at that time and were surrounded by marginal sea/ocean. There occurred several passive continental marginal seas at the periphery of the North China block; the Yangtze block was characterized by arc-basin sediments around the western, northern and southeastern margins; it was active continental margin at the Aksu area developed around the northwestern Tarim block, and passive continental margin at the Kuluketage (clast) and at the Tiekelike (carbonate) grew around the nrotheastern and southwestern part of the block, respectively. In the continental marginal sea and ocean surrounding the three blocks, many massifs had a relationship with the Yangtze and Tarim cratons, such as Yining, Dunhuang, Alxa, Songpan, Luoxiao and Wuyi, and so on. A few massifs had been related to the North China and Siberian cratons, such as Baoyintu, Xilinhot, Ergun, Hanjiayuan, Jiamusi and Altay blocks. |
