| 摘 要： | 甘肃省的构造部位独特,构造形迹十分复杂。本文在总结前人研究成果和结合近年来的研究进展的基础上,对甘肃省中生代以前的古板块构造重新研究,认为甘肃省地处西伯利亚、哈萨克斯坦、塔里木、华北、柴达木—祁连和扬子6个板块的交汇处。红石山蛇绿岩带以北属西伯利亚板块,柳园—大奇山—帐房山蛇绿岩带以南属塔里木板块,西伯利亚板块和塔里木板块之间是哈萨克斯坦板块,阿尔金走滑断裂、龙首山断裂及北祁连走廊南山—毛毛山蛇绿岩带中东段以南属于柴达木—祁连板块,龙首山断裂及北祁连走廊南山—毛毛山蛇绿岩带中东段以北属华北板块,西秦岭北缘天水关子镇蛇绿岩带是柴达木—祁连板块和扬子板块的分界。又据板内的深断裂和建造特点进一步划分为12个二级单元和22个三级单元。

| Abstract: | The tectonic location of Gansu Province is unique,and structural features are complex.On the basis of the results of former researchers and new progress on paleo-plate tectonics before Mesozoic,it is deemed that Gansu Province is located at convergence of such 6 plates as Siberia,Kazakhastan,Tarim,the North China,Qaidam-Qilian and Yangtze,the north to Hongshishan ophiolite zone belongs into Kazakhastan Plates,the south to Liuyuan-Daqishan-Zhangfangshan ophiolite zone into Tarim Plates,between Sibera Plates and Tarim Plates is Kazakhastan Plates,the south to A'erjin strike-slip fault,Longshoushan fault and Nanshan in north Qilian corridor-the east and middle section of Maomaoshan ophiolite zone belongs into Qaidamu-Qilian Plates,the north to Longshoushan fault and Nanshan in north Qilian corridor-the east and middle section of Maomaoshan ophiolite zone into the North China,Guanzizhen ophiolite zone in Tianshui which is in the edge of west Qinling is the boundary between Qaidamu-Qilian Plates and Yangtze Plates.12 secondary units and 22 third units are divide in terms of deep fault within plate and formation. |
