The calcite mylonites in the Xar Moron-Changchun shear zone show a significance dextral shearing characteristics. The asymmetric(σ-structure) calcite/quartz grains or aggregates, asymmetry of calcite c-axes fabric diagrams and the oblique foliation of recrystallized calcite grains correspond to a top-to-E shearing. Mineral deformation behaviors, twin morphology, C-axis EBSD fabrics, and quartz grain size-frequency diagrams demonstrate that the ductile shear zone was developed under conditions of greenschist facies, with the range of deformation temperatures from 200 to 300°C. These subgrains of host grains and surrounding recrystallized grains, strong undulose extinction, and slightly curved grain boundaries are probably results of intracrystalline deformation and dynamic recrystallization implying that the deformation took place within the dislocation-creep regime at shallow crustal levels. The calculated paleo-strain rates are between 10-7.87s-1 and 10-11.49s-1 with differential stresses of 32.63-63.94 MPa lying at the higher bound of typical strain rates in shear zones at crustal levels, and may indicate a relatively rapid deformation. The S-L-calcite tectonites have undergone a component of uplift which led to subhorizontal lifting in an already non-coaxial compressional deformation regime with a bulk pure shear-dominated general shear. This E-W large-scale dextral strike-slip movement is a consequence of the eastward extrusion of the Xing’an-Mongolian Orogenic Belt, and results from far-field forces associated with Late Triassic convergence domains after the final closure of the Paleo-Asian Ocean.

The NE-striking Jiamusi-Yitong fault zone(JYFZ) is the most important branch in the northern segment of the Tancheng-Lujiang fault zone. The precise shearing time of its large-scale sinistral strike-slip has yet to determined and must be constrained. Detailed field investigations and comprehensive analyses show that strike-slip faults or ductile shear belts exist as origination structures along the western region of Yitong Graben. The strike of the shear belts trend to the NE-SW with steep mylonitic foliation. The zircon U-Pb dating result for the granite was 264.1±1 Ma in the ductile shear belt of the JYFZ. The microstructural observation(rotated feldspar porphyroclasts, S-C fabrics, and quartz c-axis fabrics, etc.) demonstrated the sinistral shearing of the ductile shear zones. Moreover, the recrystallized quartz types show a transitional stage of the subgrain rotation toward the recrystallization of the grain boundary migration(SR-GBM). Therefore, we suggest that the metamorphic grade of the shear zone in the ductile shear zones should have reached high greenschist facies conditions, and the deformation temperatures should approximately 450-500°C, which is obviously higher than the blocking temperature of muscovite(300-400°C). Hence, the ^40Ar/^39Ar isochron age of muscovite from ductile shear zones should be a cooling age(162.7±1 Ma). We infer that the sinistral strike-slipping event at the JYFZ occurred in the late Jurassic period, and it was further inferred from the ages of the main geological events in this region that the second sinistral strike-slip age of the Tancheng-Lujiang fault zone occurred during the period of tectonic movements in the Circum-Pacific tectonic domain. This discovery also indicates the age of the Tancheng-Lujiang fault zone that stretches to northeastern China. The initiation of the JYFZ in the late Jurassic is related to the speed and direction of oblique subduction of the west Pacific Plate under the Eurasian continent and is respon

The Quaternary sediments in the Yili Basin can serve as archives for studying the Cenozoic basin-mountain relationship. In this study, based on typical natural sections and boreholes, the surficial sediments of the Huocheng area were studied, and their sedimentary ages were obtained using the optically stimulated luminescence(OSL) and electron spin resonance(ESR) dating methods. These dates, combined with changes in the sedimentary facies, provided details of the neotectonic movement in the Yili Basin and adjacent areas. By dating sediments from five sections and three boreholes, we determined that the surficial sediments of the Huocheng area were mainly formed in the Late Pleistocene, with scattered instances of Holocene sediments. The surficial sediments mainly consisted of alluvial fan facies, fluvial facies, lacustrine facies, and desert facies. Based on the activity on the Hongshanzui fault and the northern margin fault of the Wusun Mountains, the Huocheng area was uplifted synchronously with the Tianshan Mountains during the last stage of the Late Pleistocene, causing the desert facies sediments to be superimposed on the former paleo-lake sediments.

华北地区中-新生代以来的构造转换作用与渤海潜山圈闭和储层成因的关系研究较少。基于岩心、镜下薄片和地震等资料,并结合区域构造背景,厘清了渤海湾盆地渤中19-6区中-新生代构造转换特征及其对潜山地层、圈闭和太古宇储层的影响。研究表明,渤中19-6区潜山构造受华北、华南和古太平洋3大板块相互作用,主要经历了前印支期—印支期、印支期—燕山期和燕山期—喜马拉雅期3次构造转换作用,形成了北西向、北东向、近南北向和东西向4组断裂体系。印支期北西向断层控制了太古宇和古生界整体的圈闭和地层展布规律;燕山期北东向和近南北向断层使潜山圈闭更加复杂化,喜马拉雅期断陷下沉,潜山整体构造面貌最终定型。多幕次构造运动对太古宇潜山大规模裂缝的形成具有重要意义,其中印支期的逆冲推覆是太古宇规模性裂缝形成的关键时期,燕山期构造转换作用进一步扩大了太古宇裂缝储层发育规模,喜马拉雅期构造转换对早期裂缝“再活化”具有显著影响,多期时-空构造转换作用是太古宇发育大规模储层的关键。提出的中国东部中-新生代构造作用与潜山圈闭和储层成因的关联机制,为中国东部潜山储层预测提供了更有效的方法途径,对指导类似盆地内的潜山油气勘探具有重要意义。

The latest sharp uplift of the Tibetan Plateau and adjacent mountains occurred at the end of the early Pleistocene. The uplift of the Plateau resulted from Late Mesozoic--Cenozoic compressional structure due to the subduction of the Indian Plate beneath the Asian continent. This event definitively effected the formation of basin-mountain relief, Cenozoic basin deformation, large scale aridity and desertification of western China. The Australasian meteorites impact event happened ca. 0.8 Ma ago, located in the triangle area of the Indian Ocean ridge (20°S/67°E). The impact may have resulted in an acceleration of speeding of the Indian Ocean ridge pushing the Indian Plate to subduct rapidly northward. Thus, the impact event can give reasonable explanation for the dynamic background of the latest rapid uplift of the Tibetan Plateau and the continental deformation of western China and even of the Middle Asia.

嫩江洋闭合机制是大兴安岭地区一个争议较大的科学问题。音德尔杂岩为大兴安岭与松辽盆地盆山结合带上新发现的一套俯冲增生杂岩,岩石强烈韧性变形,其构造变形样式及时间较好的记录了嫩江洋闭合过程。该套杂岩基质由绢云片岩、绿泥石片岩及阳起石片岩等组成,岩块主要包括闪长岩、辉长岩、玄武安山岩及花岗岩。宏观变形样式观察和微观组构分析表明,音德尔杂岩发育两期构造变形:早期变形以倾向NW的片理、片麻理及糜棱面理为标志,并发育有NNW向倾伏的构造线理,线理倾伏角一般较大,指示NW-SE方向强烈挤压背景下形成的一期逆冲线理;晚期变形以NE向倾伏的低角度矿物拉伸线理为标志,石英及长石等矿物通过晶内位错滑移与膨凸式重结晶等塑性流变方式显著定向拉长,构造形迹指示一期NE-SW走向的左行走滑剪切作用,晚期线理普遍改造或置换早期线理。两期构造变形事件分别对应兴安增生地体与松嫩地块碰撞造山早期的强烈挤压阶段和造山晚期伸展走滑调整阶段。构造岩与围岩接触关系年代学研究限定音德尔杂岩构造变形发生于早石炭世末期(323Ma)之前。早石炭世早期嫩江洋开启双向俯冲模式,在兴安增生地体东缘和松嫩地块西缘形成大量增生楔。早石炭世末期嫩江洋闭合,兴安增生地体与松嫩地块碰撞拼贴并发生强烈挤压造山,两侧增生楔在NW-SE方向汇聚应力驱使下呈花状仰冲隆起,伴随斜向走滑形成早期高角度叶理与线理。造山晚期,兴安增生地体与松嫩地块之间发生显著的左行走滑剪切作用,形成了NE-SW走向的低角度矿物拉伸线理。嫩江洋闭合相关构造的解析表明其具有双向俯冲的特征。
