吉林省喜山构造旋回运动幕次的划分

Division of movement episode of Himalayan structural cycle in Jilin Province

依据吉林省新生代沉积盆地的演化、岩石地层序列中区域性不整合接触关系的确认,结合区域火山岩的同位素年代学资料,初步确定喜山构造旋回经历了伊普尔期/路特期、普里亚本期/吕珀尔期、夏特期/阿基坦期、赛拉瓦勒期/托尔托纳期、墨西拿期/赞克尔期和皮亚琴察期/格拉斯期等6个构造运动幕,而后进入新构造运动发展期。其中普里亚本期/吕珀尔期幕为构造主幕,波及了整个中国东部,乃致改变了滨西太平洋大陆边缘的构造样式。

Based on the evolution of Cenozoic sedimentary basins and the confirmation of the regional uncon- formity contact relationship in lithostratigraphic sequences in Jilin Province, the authors confirm that the Himalayan （Xishan） structural cycle has experienced six movement episodes including Ypresian/Lutetian, Priabonian/Rupe- lian, Chattian/Aquitanian, Serravallian/Tortonian, Messinian/Zanclean and Piacenzian/Gelasian, subsequently, the Himalayan period gets into the developmental ore of neoteetonics. The Priabonian/Rupelian is the main episode of structural cycle, which effects the whole eastern China, even change the structural style of the continental margin of West Pacific Ocean region.
