论中国大陆基底构造

中国大陆基底可以分为４个区域：西域克拉通和东亚克拉通具太古代－早元古代变质基底，蒙藏增生陆块与华南增生陆块为元古代基底．在西域克拉通内可以识别出南塔里木陆核分布区、准噶尔陆核分布区与伊犁陆核；在东亚克拉通内可以勾画出燕吕陆核分布区、黄淮陆核分布区、秦岭陆核分布区和扬子陆核分布区．在克拉通形成的同时或稍后，在克拉通的两侧发育巨型基底断裂．在东亚克拉通的东西侧为郯庐断裂带与东亚克拉通西缘断裂带；在西域克拉通的南北为阿尔金断裂带与阿尔曼大断裂带．在蒙藏地块中部通过的日喀则－狼山断裂带是位于两克拉通之间的重要断裂带．

ON CONTINENTAL BASAL STRUCTURE IN CHINA

The basement in China can be divided into four regions: The West China Craton, the East China Craton, the Mongolian-Tibetan massif, and the South China massif. In West China Craton and East Asia Craton, the basement are Archean Early Proterozoic metamorphite. In Mongolian-Tibetan accreting continental massif and South China accreting continental massif, the basement are proterozoic rocks.It can be detected three continental cores distributed regions in West China Craton.i. e. South Tarim Cores, Junggar cores, and Ili core, and four cores distributed regions in East Asia Craton, i. e. Yanshan-Luliangshan cores, Huanghe-Huaihe cores, Qinling cores, and Yangtze cores. At the same time as the Craton formedor some later, at the flank of cratons developed huge faults, on the east and west side of East Asia craton are the Tangcheng-Lujiang fault and Western boundary fault. on the south and north boundaries of West China Craton are Altun fault and Almantai fault. Xigaze-Langshan fault is another important huge fault between Mongolian-Tibatan masaif.
