Re-understanding of the rising and falling Interface of each stage of Neoproterozoic period in Liaoning Province

摘要: 【研究目的】辽宁地区位于华北板块东北缘，传统观点认为华北板块自吕梁-四堡运动之后直至古生代末期，一直处于构造稳定期，没有受到明显的构造运动影响。近年来研究结果表明，辽宁地区新元古代时期构造运动相对较为频繁。前人根据大连地区1/25 万区调（2001）确认的风化夷平面，将辽宁新元古代时期的构造运动统称为晋宁运动，并划分为四个次一级构造运动，分别为万福升降运动（相当芹峪升降运动）、驼山升降运动、茶叶沟升降运动和大连升降运动，其中驼山升降运动和茶叶沟升降运动的划分定义存在不准确性，其命名有待商榷，需进一步研究探讨。【研究方法】本文以辽宁地区的新元古代地层为研究对象，以区域地质调查资料为基础，结合同位素测年资料对辽宁省新元古代升降运动进行了重新划分与定义。【研究结果】通过区域对比研究划分出晋宁运动和大连运动两个旋回和七个次一级的升降运动，并将其对应于三次冰期、两次间冰期以及冰期前和冰期后。七个次一级的降运动分别命名为芹峪升降、殷屯升降、大孤山升降、太子河升降、复州升降、南关岭升降和大连升降。殷屯升降、大孤山升降、太子河升降、复州升降和南关岭升降等五个次一级构造运动，本次统称之为晋宁运动，代表新元代早期的构造运动；新元古代中晚期（约890～541 Ma），辽宁地区缺失原兴民村组之上地层，代表新一期构造运动抬升的产物，本次将该期运动称之为大连运动，与西北的柯坪运动和南方的澄江运动基本相当。芹峪升降界面标志着四堡运动的结束和晋宁运动的开始；青白口系周家崴子组和王家坦子组之间的沉积间断称为南关岭升降，南关岭升降界面标志着晋宁运动的结束和大连运动的开始；大连升降界面（约541 Ma）的确认，标志着新元古代大连运动的结束和早古生代兴凯运动的开始。【结论】辽宁地区新元古代早期构造运动较为频繁，存在三次冰碛作用和多处平行不整合界面，可划分为晋宁运动和大连运动两个旋回以及七个次一级的升降运动，为区域地层研究对比提供重要参考资料。Abstract: This paper is the result of regional geology.[Objective] Liaoning area is located in the northeast margin of the North China plate.The traditional view is that Liaoning area has been in a period of tectonic stability from the Lv Liang-Sibao movement to the end of the Paleozoic era and has not been affected by the obvious tectonic movement.However, In recent years, the results show that the Neoproterozoic tectonic movement in Liaoning area is relatively frequent.According to the weathering-planation surface confirmed by Liaoning 1:250 000 Dalian regional surveys(2001), the tectonic movement in Neoproterozoic period in Liaoning Province was collectively called Jinning Movement, and divided into four sub-tectonic movements, namely, Wanfu vertical movement (equivalent to Qinyu vertical movement), Tuoshan vertical movement, Chayegou vertical movement and Dalian vertical movement.Among them, There is an inaccuracy in the classification and definition of the vertical movements of Tuoshan vertical movement and Chayegou vertical, and their naming needs further research and exploration.[Methods] This paper takes the Neoproterozoic strata in Liaoning Province as the research object, based on regional geological survey data and combined with chronological data, to redefine the Neoproterozoic vertical movement in Liaoning Province.[Results] Through regional comparative research, two cycles of Jinning Movement and Dalian Movement, as well as seven sub level vertical movements, were identified, corresponding to three glaciation, two interglacial periods, and pre and post glacial periods.The seven sub level vertical movements are named Qinyu vertical movement, Yintun vertical movement, Dagushan vertical movement, Taizihe vertical movement, Fuzhou vertical movement, Nanguanling vertical movement, and Dalian vertical movement.The five sub level tectonic movements, including the Yintun vertical movement, Dagushan vertical movement, Taizihe vertical movement, Fuzhou vertical movement, and Nanguanling vertical movement, are collectively referred to as the Jinning movement, representing the early tectonic movement of the Neoproterozoic period.In the mid to late Neoproterozoic era(about 890-541 Ma), the strata above the original Xingmincun Formation were missing in the Liaoning region, representing the product of the uplift of the new tectonic movement.This movement is referred to as the Dalian Movement, which is similar to the Keping Movement in the northwest and the Chengjiang Movement in the south.The Qinyu lifting interface marks the end of the Sibao Movement and the beginning of the Jinning Movement.The sedimentary discontinuity between the Zhoujiaweizi Formation and Wangjiatanzi Formation of the Qingbaikou System is called the Nanguanling vertical movement.The Nanguanling uplift and subsidence interface marks the end of the Jinning Movement and the beginning of the Dalian Movement.The confirmation of the Dalian lifting interface (about 541 Ma) marked the end of the Neoproterozoic Dalian Movement and the beginning of the Early Paleozoic Xingkai Movement.[Conclusions] The early Neoproterozoic tectonic movements in the Liaoning region were relatively frequent, with three glaciation and multiple parallel unconformity interfaces, which can be divided into two cycles:the Jinning Movement and the Dalian Movement, as well as seven sub level vertical movements, providing important reference materials for regional stratigraphic research and comparison.
