【摘要】 天山造山带与准噶尔盆地、塔里木盆地之间的盆-山耦合关系研究是中国地学界的一个热点研究课题。许多研究者从不同角度对其进行了专门的探讨,但仍存在意见分歧,主要原因在于对其中若干重要地质接触关系缺乏系统的观测,尤其对关键性地层关系的认定缺乏可靠的依据。通过6幅1∶5万区域地质调查,在天山造山带内部的后峡—艾维尔沟地区晚古生代—中生代地层系统中发现和厘定了5个不整合面,从而为天山造山带的演化及其与两侧盆地盆-山耦合关系的研究提供了新的地质证据。更多还原

【Abstract】 The basin-range coupling between the Tianshan orogenic zone and the Junggar basin and Tarim basin is a hot spot of geoscience research in the geoscience community of China. It has been studied by many researchers from different aspects, but diverse views still exist. The main cause is due to the lack of systematic observations on several important geological contact relationships, especially the lack of reliable evidence for the determination of the relationships among the key stratigraphic units. Through six sheets of 1∶50000 regional geological survey, five unconformities in the Late Paleozoic-Mesozoic stratigraphic system have been found and defined in the Houxia-Ewirgol valley area of the Tianshan orogen interior, thus providing new geological evidence for the study of the tectonic evolution of the Tianshan orogen and its coupling with the basins at both sides.更多还原
