    • 摘要: 对于朝鲜平南盆地沉积盖层内发育的倒转褶皱,过去一般认为是直立褶皱的次级从属褶皱.通过对平南盆地内倒转褶皱发育区详细的地质调查,结合煤炭开发过程中获得的地质及钻探资料,提出平南盆地内叠加褶皱的主要识别标志为:地质平面图上呈现不同类型的两组褶皱脊线的交叉;倒转褶皱的轴面被直立褶皱改造弯曲;直立褶皱的两翼发育的倒转褶皱表现为两组牵引褶皱.查明了平南盆地存在3个阶段的褶皱构造:第一阶段为东西向的倒转褶皱,形成于印支期;第二阶段褶皱为东西向的直立褶皱,形成于早燕山期;第三阶段褶皱为北北东向的直立褶皱,形成于晚燕山期.

    • 摘要: The tectonic attribute of the capping fold developed in Paleozoic-Early Mesozoic in the northeastern margin of Jiangnan orogen is gradually recognized, but there is not research report about the superposed folds and their superposed patterns in the study area at present.Based on the field investigates, Caledonian and Indosinian fold structures develop in the northeastern margin of Jiangnan orogen.Based on the characteristics of the superposed folds and the restoration of stress field, the geometry and kinematics characteristics of superposed folds are discussed by structure analysis and stereographic projection method, and there are three stages of the capping superposed fold deformation, including the first fold (F1), the second fold (F2) and the third fold (F3).In the early stage, the cap suffers SN compression, and forms Late Caledonian EW-nearly fold (F1);then, the first fold suffers SE-NW compression, and forms Early Indosinian NE or NNE fold (F2);in the later stage, the second fold suffers NE-SW compression, and forms Late Indosinian-Early Yanshanian SN-nearly or NNW fold (F3).The regional superposed folds mainly have vertical span and slant span styles, and develop various Interference patterns.The results show that the second fold diagonally overprints the first fold, and forms the basic structural pattern in the area.The study on the structural characteristics and deformation evolution of superposed folds has great significance on the reconstruction of tectonic framework and geological prospecting.%江南古陆东北缘古生代—早中生代盖层中发育的褶皱构造属性逐渐被认识,但该区是否存在叠加褶皱及其叠加样式如何则未见报道.通过野外调查,发现江南古陆东北缘发育加里东期、印支期褶皱构造.通过对区内叠加褶皱特征和应力场恢复研究,并应用构造解析和赤平投影法研究叠加褶皱的几何学和运动学特征,显示盖层发育3期区域性叠加褶皱变形:区内早期遭受SN向挤压,形成加里东晚期近EW向褶皱(第一期褶皱);其后遭受SE—NW向挤压,形成印支早期NE向或NNE向褶皱(第二期褶皱);晚期遭受NE—SW向挤压,形成印支晚期—燕山早期近SN向或NNW向褶皱(第三期褶皱).区域叠加褶皱主要有横跨和斜跨叠加褶皱,发育多样干涉样式.结果表明:第二期褶皱斜跨第一期褶皱,形成了区内基本构造格局.深入研究叠加褶皱构造特征和变形演化史,对区内构造格架重建和地质找矿均具有重要意义.

    • 摘要: 内蒙古东南部西拉木伦断裂两侧二叠纪地层中发育有一系列叠加褶皱, 它们与侏罗纪地层内部褶皱及断裂变形记录了该区晚古生代以来的多期构造事件.研究这些变形对探索华北北部及邻区所经历的从古亚洲构造域到古太平洋构造域转换的动力学过程具有重要意义.二叠纪、侏罗纪地层变形的详细地质填图及叠加褶皱构造样式与区域演化序列的研究, 揭示出:二叠纪地层褶皱形迹具S型展布特征, 总体走向NEE, 轴面倾向NW;中生代地层褶皱走向NE, 轴面倾向SE, 伴生逆冲断层多向SE倾斜并且上盘向NW逆冲.研究厘定区内经历三期构造变形: (D1) 二叠纪末—中三叠世NNW-SSE向区域性挤压, 二叠纪地层形成NEE向褶皱; (D2) 晚三叠世区域性剪切作用将先期形成的NEE向褶皱改造成平面弧形褶皱, 表现为Simón (2004) 划分的Type2a与Type1d型叠加褶皱样式; (D3) 晚侏罗世NW-SE向挤压导致中侏罗世地层中倒向NW的褶皱构造, 并使得二叠纪地层褶皱更加紧闭.研究认为这三期变形可能分别代表: (1) 古亚洲洋闭合和伴生的碰撞造山作用; (2) 介于西拉木伦右行走滑断裂与蒙古东南部东戈壁左行走滑断裂之间块体的NEE向挤出构造; (3) 古太平洋板块向欧亚大陆之下的俯冲作用.%Multi-scale fold interference patterns developed in the Permian strata on both sides of the Xar Moron fault, southeastern Inner Mongolia.These superimposed folds and the deformation within the Jurassic strata recorded multiple tectonic events in the research area since the Permian.Research on these deformations is crucial for a better understanding of the tectonic evolution from the Paleo-Asian system to the Paleo-Pacific system along the northern margin of the North China Block.In this study, we employed detailed field mapping to decipher the geometry of these superimposed structures and their evolution.Folds distributed in the Permian strata are characterized by sinuous axial trace with southeast verging.Folds in the Mesozoic strata, however, are trending southeast with northwest verging.Three tectonic deformation phases were identified in this research: (D1) East-northeast trending folds in the Permian strata implying a north-northwest-south-southeast compression from the end of the Permian to the Middle Triassic; (D2) Regional shear events during the Late Triassic resulting in the formation of the Type2 aand Type1 dfold interference patterns proposed by simon, 2004;and (D3) Northwest-verging folds within the Middle Jurassic strata thought to be developed under a northwest-southeast compression during the Late Jurassic.Furthermore, D3 deformation led to fold tightening within the Permian strata.We interpret these three deformation phases (D1, D2, D3) as the consequences of the final closure of the Paleo-Asian Ocean and collisional orogeny, the east-northeast extrusion of blocks between the dextral strike-slip of the Xar Moron fault in northern China and the sinistral strike-slip East Gobi Fault in southeastern Mongolia, and the westward subduction of the Paleo-Pacific oceanic plate under the Eurasian plate, respectively.

    • 摘要: 湘南江永地区处于华夏陆块西北缘,自早古生代以来经历了多期构造变形,关于这些变形的研究对探索湘南地区及其邻区的构造演化过程具有重要意义。通过对江永地区古生界褶皱的构造要素测量和褶皱叠加关系的解析,识别出了3期4个方向的褶皱构造,按发育早晚顺序分别为第一期(D1)NE向褶皱,第二期(D2)NNE-近SN向褶皱、NW向褶皱,第三期(D3)近EW向褶皱。其中D1期NE向褶皱为下古生界独有的构造样式,本区及邻区上古生界仅记录了后2期(D2和D3)3个方向的褶皱作用。结合地层接触关系、岩浆活动及区域构造演化的综合分析,3期褶皱作用分别对应早古生代后期加里东陆内造山运动NW向挤压、中三叠世后期印支运动NWW向挤压以及晚三叠世-早侏罗世近SN向挤压等构造事件。

    • 摘要: 贵州南盘江盆地发育一系列不同样式的穹隆状构造,其控制着低温矿床的分布,位于黔西南控制烂泥沟超大型金矿床的赖子山穹隆是其典型代表.在统计赖子山穹隆地层产状的基础上,通过π圆图解确定出轴迹分别为NW和NE向的稳定变形亚区,并依据亚区构造横剖面和几何投影解析得到亚区褶皱位态类型均为直立水平背斜.通过统计分析区内劈理并依据劈理与亚区褶皱轴面的平行关系筛选出轴面劈理,基于轴面劈理的切割关系、卷入变形的地层及前人获得的相关构造岩浆岩年代推断出组成赖子山穹隆亚区褶皱的发育时序,即NW-SE向背斜发育于燕山早期,NNE-SSW向背斜发育于燕山晚期.基于地质构造分析,结合该地区地层岩石能干性强弱、地层缩短量和变形边界条件建立两个沙箱模型进行4组实验,通过改变软弱层材料、变形同时性模拟构造复合叠加和构造联合叠加的变形过程及样式,讨论影响叠加变形的因素.根据模拟结果,我们认为赖子山穹隆是NW向和NNE向纵弯直立水平褶皱经移褶性复合叠加形成的穹隆状构造,两期褶皱分别对应燕山早期雪峰山隆起对南盘江盆地的侧向挤压作用和燕山晚期黔西南由NW向SE的大型逆冲推覆作用;岩层能干性差异和构造变形的强弱是影响叠加褶皱构造样式和叠加类型的关键因素,当岩层能干性差异较大时,相对软弱的岩层起到分层变形作用,使得软弱层上下强硬层构造样式不同;后期变形较弱时,形成限制性、移褶性叠加褶皱,后期变形较强时,形成斜跨、横跨式叠加褶皱,分阶段变形形成复合叠加构造,同时变形或变形速度差较小时,形成弧形的联合叠加构造.%The Nanpanjiang Basin develops a series of tectonic domes which control the distribution of low-temperature mineralization.An example is the typical Laizishan Dome,it controls the Lannigou giant gold deposit in the southwest Guizhou Province.Based on the statistics of strata attitude around the Laizishan Dome,the studied area was subdivided into NW and NE sub-regions through π circle projection analysis,and the fold type in the subregion was confirmed to be upright horizontal anticline by cross section and geometric projection analysis.Selection of axial plane cleavages was made based on statistics of all cleavages and parallel relationship between cleavage and axial plane of fold in the subdistrict.According to cross-cutting relationships of axial plane cleavages,and age of strata and related intrusion involved in the deformation,the sequence offold development in the subdistrict and age of deformation were constrained,consequently inferring that the NW-SE-and NNE-SSW trending anticlines were developed in the early and late Yanshanian,respectively.In the structural analysis based on the stratigraphic strength,strata shortening and deformation boundary conditions,four groups of sandbox simulation experiments with two sandbox models were designed to study the process and types of tectonic compounding and conjunction;and factors affecting the superposed deformation are discussed.The simulation results suggest that the Laizishan Dome is the result of superposition the NNE-and NW-trending buckling folds,and the type of superposition is a migration of fold superimposition.Furthermore,the two folds correspond to the lateral extrusion to the Nanpanjiang Basin by the Xuefengshan uplift during the early Yanshanian,and the large-scale thrusting from NW to SE in southwest Guizhou during the late Yanshanian,respectively.The results also show that difference in rock strengths and deformation intensities are the main factors affecting the styles and types of superimposition:when strength difference is large,the weak layer affects the structural styles of the upper and lower hard layers;when later stage deformation is weak,limited or migrating superimposed fold is formed,otherwise it forms the oblique crossing or crossing superimposed fold;and phased deformation leads to tectonic compound superposition,whileco-instantaneous deformation or lesser difference in deformation velocity results in curved tectonic conjunction superposition.

    • 摘要: Northeastern Yunnan,located in the southwestern part of the Yangtze Block,developed a series of tectonic domes hosting low temperature or closely related deposits.Research on the structural origin and properties of these tectonic domes is beneficial for revealing the regularity of regional low temperature ore formation.The Jiache Dome in northeast Yunnan situates near Awang and Jiache towns.Compared with other domes in the area,the Jiache Dome developed a complete structure-rock assemblage,typical of the regional tectonic domes.Focusing on the structural features of the Jiache Dome,the structural origin and deformation sequences of tectonic domes,characteristics of background anomaly of low temperature metallogenic elements,and occurrence of Pb,Zn,Ag,As,Sb elements were determined in this work,through detailed geological investigation,structural analysis,key stratum sample collection,geochemical and EMPA analyses,in combination with regional background data.By completing three crosscutting structural profiles of the Jiache Dome,it is discovered that the dome has experienced at least three stages of structural deformation (D1,D2,D3):D1 period developed consequent flow layer deformation,possibly of the Caledonian age;D2 period formed the NEE trending buckling fold with a supposed deformation age of the Indosinian;D3 period resulted in the NNE trending buckling fold,whose deformation age is postulated to be the Yanshanian.Results of geochemical analyses show that low grade metamorphic rocks in the Kunyang Group (for example muddy and silty slate)have background anomaly values 3 to 5 times higher than background levels for Pb,Zn,Ag,Sb,As and siltstone in the Chengjiang Formation of Sinian.Similarly,dolomite and black shale in the Dengying Formation exhibit background anomaly levels 3 to 5 times higher than background values for Pb,Ag,and As.And part of black shales in the Yuhucun Formation of the lower Cambrian show background anomaly values 5 times higher than background values for Pb,Zn,Ag,Sb,As.EMPA analysis suggests that these low temperature ore-forming elements are mainly hosted in the primary pyrite.Results of structure analyses further show that the main body of the dome formed over the superposed NNE-and NEE-trending folds,and it has experienced multi-stage tectonic superposition and transformation.%滇东北地区位于扬子地块西南部,该区域内发育一系列直接赋存有低温矿床或与低温成矿作用联系密切的构造穹隆体.详细研究这类穹隆体的构造成因及属性,是揭示区域内低温成矿规律的关键.驾车穹隆位于滇东北阿旺镇至驾车乡一带,与滇东北其他穹隆体相比,驾车穹隆出露完整的构造-岩石组合,是该区域构造穹隆体的典型代表.文中以驾车穹隆的构造特征为研究对象,通过详细的地质构造调查与构造解析、重点地层系统样品采集并进行地球化学分析及电子探针分析,结合区域背景资料,确定了穹隆的构造成因及变形序列、主要低温成矿元素背景异常特征及赋存状态.通过对3条横切驾车穹隆体构造剖面的构造解析,厘定了3期构造变形:D1期顺层流变构造,变形时代推测为加里东期;D2期为NEE向纵弯褶皱,变形时代推测为印支期;D3期为NNE向纵弯褶皱,变形时代推测为燕山期.地球化学分析结果表明:穹隆内昆阳群中泥质和粉砂质板岩等低级变质岩中具有3~5倍以上Pb、Zn、Ag、Sb、As元素背景异常;震旦系澄江组粉砂岩、灯影组白云岩与黑色页岩中局部具有3~5倍以上Pb、Ag和As的元素背景异常;下寒武统渔户村组部分黑色页岩中具有5倍以上的Pb、Zn、Ag、Sb、As元素背景异常.电子探针分析结果进一步表明,上述低温成矿元素在原生黄铁矿中富集.综合构造解析结果表明,驾车穹隆主体是一个由NNE向褶皱(D3期)横跨叠加于NEE向褶皱(D2期)之上而形成的构造穹隆体,为印支期与燕山期构造复合的结果.
