In eastern China, the Dabie Shan–Su–Lu orogenic belt has been separated by the Tan–Lu sinistral strike–slip fault. Mylonites are exposed along the strike–slip fault system in the southern segment, and along the eastern margin of the Dabie Shan orogenic belt. The country rocks of the mylonites are retrograde UHP eclogites, gneissic granites, muscovite granites and gneisses. The ductile strike–slip shear zone trends 30–40°N (NE30–40°‐trending) and exhibits stretching lineations and nearly vertical, SE‐dipping foliations. Most of the zircon grains separated from mylonites have a weighted average radiometric age of 233 ± 6–225 ± 6 Myr. These data constrain the onset of the Tan–Lu sinistral strike–slip movement and imply that the Tan–Lu sinistral strike–slip motion developed after retrograde UHP metamorphism. The related phengite within the eclogite rocks on the western side of the Tan–Lu fault, with 40Ar/39Ar plateau ages of c. 182–190 Myr, is also deformed and aligned parallel to the almost NE trending stretching lineations. Non‐metamorphosed granites exhibit sinistral strike–slip shearing and indicate that the Tan–Lu fault initially developed after 182–190 Myr. Muscovite collected from the mylonite yields 40Ar/39Ar plateau ages of 162 ± 1–156 ± 2 Myr. The zircon SHRIMP age data, the muscovite 40Ar/39Ar plateau ages, together with structural and petrological field information support the interpretation that the Tan–Lu strike–slip fault was not related to the Yangtze–north China plates collision, but corresponded to the formation of a NE‐trending tectonic framework in eastern China starting c. 165–160 Ma. 相似文献

湘赣边区NNE向走滑造山带构造发展样式 总被引：63，自引：2，他引：61
应用马杏垣教授倡导的构造解析方法,对湘赣边区ＮＮＥ 向走滑盆岭山链的构造发展过程及样式进行了研讨,论证了该地区前中生代ＥＷ 向古特提斯构造体系与中新生代ＮＮＥ向滨太平洋构造体系之间的立交桥式横跨叠加关系和构造背景,建立了华南陆壳俯冲 会聚走滑转换造山模型,提出了新华夏式变质核杂岩构造的新概念,并对其基本特征和形成机制进行了阐述。文中强调,发育在湘赣边区的ＮＮＥ 向走滑断裂是郯庐断裂带南段的主干成分,由ＮＥ３０°同向走滑断裂（Ｐ） 和ＮＷ３２０°反向走滑断裂（Ｒ′） 交织而成的雁列菱形网结系统是该断裂在地表的基本构造样式。大多数陆壳俯冲型和会聚走滑型的花岗岩都具剪切重熔成因,雁列的半地堑盆地和新华夏式变质核杂岩体主要受走滑 伸展变形场所控制。指出自晚三叠世以来,该地区曾经历了两次不同的重大构造转换和两个性质及发展趋向相反的走滑造山过程,即印支晚期的陆壳俯冲向陆内会聚走滑转换和侏罗纪时期的会聚走滑造山;早白垩世开始的会聚走滑向离散走滑转换和白垩纪－ 老第三纪的离散走滑造山。每次构造转换和构造变形对该地区的成岩成矿都起到了重要的作用。 相似文献

Thermal Evolution of the Tanlu Fault Zone on the Eastern Margin of the Dabie Mountains and Its Tectonic Implications 总被引：7，自引：3，他引：4
ZHU Guang HOU Minjin WANG Yongsheng LIU Guosheng NIU Manlan School of Resource Environment Engineering Hefei University of Technology Hefei Anhui Geological Survey of Anhui Hefei Anhui 《《地质学报》英文版》2004,78(4):940-953
Five samples of muscovite from mylonites of the earlier Tanlu ductile shear zone on the eastern margin of the Dabie Mountains yield 40Ar/39Ar ages ranging from 178 Ma to 196 Ma. Three of them have reliable plateau ages of 188.7±0.7 Ma, 189.7±0.6 Ma and 192.5±0.7 Ma respectively, which indicates a syn-orogenic, sinistral strike-slip thermal event. This displacement movement derived from the continent-continent collision of the North and South China blocks took place in the Early Jurassic and after uplifting of high-pressure to ultrahigh-pressure slabs to the mid-crust. It is suggested that during the collision the Tanlu fault zone was an intracontinental transform fault caused by differential subduction speeds. The 40Ar/39Ar ages of mylonite whole-rock and muscovite from the later Tanlu ductile shear zone suggest another sinistral strike-slip cooling event at 128 Ma. During this strike-slip faulting, large-scale intrusion and doming uplift occurred in the eastern part of the Dabie orogenic belt. Data o 相似文献

近年来在郯庐断裂带内获得了大量的同位素年龄,为了解该断裂带的演化规律与相关动力学过程提供了有效的制约。该断裂带早期走滑构造带内给出了238～236 Ma的白云母 40Ar/39Ar 变形年龄,指示其起源于华北与华南克拉通碰撞过程的深俯冲阶段,支持其造山期陆内转换断层成因观点。其晚中生代走滑韧性剪切带内已获得的较大白云母 40Ar/39Ar冷却年龄为162～150 Ma,表明其再次左行平移发生在晚侏罗世初或中 晚侏罗世之交,出现在区域压扭性动力学背景下。这一事件应代表了中国东部滨太平洋构造域的开始时间。已获得的一系列断裂带内岩体与火山岩锆石LA ICPMS年龄显示,该断裂带内伸展性背景下最早的岩浆活动时间为136 Ma。而断裂带所控制的断陷盆地内地层时代表明其伸展活动发生在早白垩世初（约145 Ma）。这应指示了中国东部转变为伸展性动力学背景的时间。该断裂带一系列长石40Ar/39Ar年龄与磷灰石裂变径迹年龄,显示其在晚白垩世与古近纪仍处于伸展活动之中。 相似文献

The Tan–Lu fault is a well-known active fault belt in eastern China that has been the focus of geologic studies over the past 40 years. Since the late 1990s, numerous geophysical and geological investigations of this dislocation zone have been carried out by Chinese oil companies, as well as by universities. However, its deep structure, active periods of slip, and fault mechanism remain obscure. This study focuses on the deep structures within the Jiashan–Lujiang segment of the Tan–Lu fault belt, using high-precision geophysical tools, including magnetotelluric and magnetic sounding, and artificial seismic exploration using active source methods. Our results suggest that this segment is composed of several sub-faults. The southern part of the Tan–Lu fault belt, along the Jiashan–Lujiang sub-fault, can be divided into two parts on the basis of contrasting geological features. The Chihe–Taihu sub-fault is taken as the boundary between the two. The region east of the Chihe–Taihu sub-fault is dominated by strike–slip activity along several sub-faults. Only the Jiashan–Lujiang sub-fault is exposed at the surface, forming a large, positive flower structure, the result of late Middle Jurassic to early Late Jurassic strike–slip movement along the dislocation zone. Three sub-faults are present in Dingyuan County, two of which disappear in the southern Hefei Basin. Only the Chihe–Taihu sub-fault extends to the eastern edge of this basin, creating a half-graben depression that formed during the Early Cretaceous. Our results indicate that the present-day deep structure of the southern portion of the Tan–Lu fault zone is the result of a combination of strike–slip and extensional tectonics. 相似文献

河北省兴隆县一带地处燕山造山带的中段，是中生代构造变形的典型地区。该区广泛发育了东西向和北东向联合构造，东西向主走滑断裂呈右行右阶式（Ｐ断裂），北东向次级构造由北盘的雁列式褶皱、分枝断裂及南盘次级断裂等组成。燕山台褶带变形是由尚义─平泉断裂和密云─洪山口断裂在侏罗纪时发生右行走滑形成的，其间的剪切变形带，总体特征类似于一个大型Ｓ─Ｃ构造或平面对冲构造。区内古基底断裂不仅控制中晚元古代的沉积地层和岩浆活动，而且对中生代的构造变形方式也产生重要作用。主走滑断裂与古基底断裂的复活有直接的关系 相似文献

西南三江构造体系突出表现为以昌都-兰坪-思茅地块为中轴的不对称走滑对冲构造,次为与走滑断裂相伴的伸展滑脱、走滑拉分盆地构造体系,再次为块体内部的近北东、北西向走滑断裂系。西南三江造山带构造体系演化分为挤压收缩变形、走滑深熔热隆、走滑剪切伸展、走滑剥蚀隆升等4个阶段。自晚白垩世开始,印度板块与欧亚板块碰撞,西南三江造山带对冲体构造体系初始形成。自渐新世开始,印度板块持续向北楔入欧亚大陆,印度板块与扬子克拉通构成力偶,两者相向、相对运动,挤压与剪切特提斯大洋缝合带及两大陆边缘弧盆系等地质体,西南三江造山带对冲体构造体系进一步发展,近南北向剪切走滑构造体系形成,构造方向也由近东西转为近南北向。而与近南北向主走滑断裂带之相伴的伸展滑脱构造、拉分盆地,块体内部近北东、北西“X”型剪切走滑断裂同时相伴形成。这样,就形成了西南三江造山带大规模的对冲、走滑、旋转及其伴生的伸展、拉分盆地构造的构造体系。 相似文献

大巴山构造带是秦岭造山带南部发育的一个以逆冲推覆构造为特征的构造带。通过在大巴山弧形构造带中段渔渡地区进行的详细构造解析发现,大巴山构造带在侏罗纪以来经历了至少两期变形叠加,变形地层三叠系嘉陵江组—侏罗系沙溪庙组。早期变形以与滑脱构造相关的轴向北西—北北西向箱状或隔挡状褶皱为主,并在深部发育顺层滑脱构造,变形时代为晚侏罗世到早白垩世。晚期变形与北侧逆冲相关,导致右行走滑变形,主要形成右行走滑断层和北西—北北西向紧闭褶皱,变形时代比第一期稍晚,为晚侏罗世之后到早白垩世。两期变形形成的褶皱延伸方向一致,与区域构造线的方向协调,而且在远离北侧镇巴断裂的地区变形强度有减弱的趋势,两期变形叠加形成共轴或斜交叠加构造。研究表明,变形与大巴山冲断—推覆构造带向南逆冲有关。 相似文献

文中通过对晚石炭世至早三叠世华南和华北地块古地理特征以及地层学证据的分析,认为中国东部的郯庐断裂带自海西期以来经历了两个主要发展阶段：第一阶段是广义的郯庐断裂带发展阶段,在海西期它是扬子地块北东缘呈宽缓弧形展布的边缘裂陷槽(或盆地)的边界;在印支期由于扬子地块与华北地块的碰撞,成为两地块的对接边界,具有逆冲推覆的性质,属广义的特提斯构造域。第二发展阶段从燕山期以来,发展成为一条平移断裂带,属于狭义的环太平洋构造域的平移系统。自晚石炭世至早三叠世的中国南方及华北东南部的岩相古地理资料显示了扬子地块与华北地块的对接始于晚二叠世早期,地块的抬升自南向北、自南东向北西方向呈迁移趋势;印支期的郯庐断裂带是一条北东、北北东展布的缓‘S’形的地块拼贴边界,在现今的郯庐断裂带上表现为残留的由北北西向南南东的斜向逆冲推覆的性质,表现为大别苏鲁造山带的中上部构造层的变形,即张八岭构造带及前陆褶皱冲断带的变形;燕山期以来则为众所周知的狭义的郯庐断裂带即郯庐平移断裂系统的一部分。 相似文献

关于汶川地震发震机制 总被引：10，自引：0，他引：10
2008年5月12日汶川8级地震的发震断层是四川龙门山逆冲带的前锋灌县—安县断层,或此断层附近新产生相同产状的断层。发震断层走向NE倾向NW,逆冲兼右行平移。汶川地震的发震机制是印藏陆-陆碰撞后,印度次大陆活塞状嵌入欧亚板块造成青藏高原东部向SEE方向近水平挤压,在龙门山冲断带前锋向东南逆冲到四川盆地,构造应力积累和释放的结果。汶川地震演示了一个青藏高原东缘龙门山隆起的构造模型,即其经由龙门山冲断带的地壳冲断作用和缩短作用而隆升。这与Burchfiel的模型不同,该模型认为龙门山上升是由于韧性下地壳流受到四川盆地高强度地壳阻挡而上涌所致。这两种模型可能各有其适用时间阶段,然而本文的模型是不可或缺的,因汶川地震已显示了它的真实性。 相似文献
