| 摘 要： | 通过对大量野外露头资料的详细分析,结合前人对该区的研究成果,对北祁连山—阿拉善地区的地层划分,构造演化及沉积相类型进行了研究。对香山群、韩母山群进行了重新厘定,将香山群的时代厘定为寒武纪—奥陶纪,韩母山群厘定为震旦纪—寒武纪。在研究区共识别出4种沉积相类型：海岸相、浅海相、半深海相及深海—洋盆相。在上述研究的基础上,采...

| Abstract: | Based on the vast field outcrop data analysis,integrated with the completed research achievements,stratigraphic division,structure evolution and sedimentary facies of the Cambrian in North Qilian Mountain-Alxa area are studied.Redefining of the Xiangshan group and Hanmushan group,we define the age of Xianshan group as the Cambrian-Ordovician period and the age of Hanmushan group as the Sinian-Cambrian period.Four sedimentary facies types are recognized,there are coastal facies,neritic facies,bathyal-abyssal... |
