tectonic morphology
相关语句
  构造地貌
     The mechanism of the formation of the tectonic morphology is inferred as: the collision between the Philippine plate and in turn,the Eurasian plate causes the backarc spreading and the tectonic morphology perpendicular to the axis of the Okinawa Trough,and in turn,the backarc spreading causes the linear seamounts and echelon tectonic depressions along the axis.
     对构造地貌的成因机制进行了推测,认为菲律宾板块和欧亚板块间的相互作用是产生与海槽走向垂直的构造形态和弧后扩张的动力源,而弧后扩张则产生了沿海槽走向分布的线性海山和雁行排列的构造洼地。

The Pinghu Formation, which is the major hydrocarbon-generating horizon in the Xihu Depression of the East China Sea, was in the threshold of hydrocarbon generation during the sedimentation period of the Huagang Formation and has good conditions for hydrocarbon generation and expulsion.

The Pinghu Formation, which is the major hydrocarbon-generating horizon in the Xihu Depression of the East China Sea, was in the threshold of hydrocarbon generation during the sedimentation period of the Huagang Formation and has good conditions for hydrocarbon generation and expulsion. Multiple tectonic movements changed tectonic morphology and impelled hydrocarbon migration. The study of computer simulation showed that the migration directions of hydrocarbon in the Xihu Depression were mainly the west slope zone and the central anticline zone. The west slope zone was dominated by lateral migration, and pools were formed by fault barriers and lithologic seals, especially in the Pinghu area. The central anticline zone was dominated by vertical migration, pools were formed in regional anticlinal structures, and pool-forming traps were closely related to fault-depression superimpositon. Besides accumulating and forming pools in the Xihu Depression, the hydrocarbon in the Pinghu Formation of the Xihu Depression probably migrated to the circumferential areas.

平湖组是东海西湖凹陷的主力生烃层位,花港组沉积时就已经进入生烃门限,具有良好的生排烃条件。多次构造运动改变了构造面貌,促使油气运移。计算机模拟研究表明,西湖凹陷的油气运移方向主要是西部斜坡带和中央背斜带。西部斜坡带以侧向运移为主,断裂隔挡和岩性封隔成藏,重点地区是平湖地区。中央背斜带以垂向运移为主,局部背斜构造成藏,成藏圈闭与断坳叠加关系密切。西湖凹陷平湖组的油气除了在西湖凹陷聚集成藏之外,有可能向周边地区运移。

Derailed structural analyses and interpretations indicate that Yud on g area has undergone three development stages from weak orogeny and stable crato nic basin during Late Proterozoic-Paleozoic, strong orogeny and peripheral fore land basin during Mesozoic to post-orogenic and residual basin during Cenozoic, and the modern structural pattern and mode are actually resulted from compound, association and superposition of multiple stages of tectonic deformations.

Derailed structural analyses and interpretations indicate that Yud on g area has undergone three development stages from weak orogeny and stable crato nic basin during Late Proterozoic-Paleozoic, strong orogeny and peripheral fore land basin during Mesozoic to post-orogenic and residual basin during Cenozoic, and the modern structural pattern and mode are actually resulted from compound, association and superposition of multiple stages of tectonic deformations. As a whole, the study area can be divided into three structural layers. The regional tectonic morphology is in a thin-skin structural pattern of advance propagatio n-type thrust nappe, and the local tectonics occurs in seven variant patterns. Here in the lower structural layer occur duplex structures and fault-bend folds , in the middle structural layer occur fault-bend folds and fault-propagation folds, while in the upper structural layer mainly occur surge folds, fault-prop agation folds and pop-up structures. Formation of these structures involves thr ee stages from Late Yanshanian, Early Himalayan and Late Himalayan. Generally, t he west-thrusting and NE-trending thrust structure system was formed earliest, the SE-thrusting and NEE-trending thrust fold system was formed secondly, and the east-thrusting and NNE-SN-trending thrust fold system was formed last. T he structure in the north of the study area was formed earlier than that the mid dle and south. The NWW-EW-trending nappe fold system in the north end actually disturbed and constrained the northward extension of the NE-NEE-trending thru st nappe system in the middle-north, while the transform (regulation) zone as d eveloped in the middle has obvious accommodation effect.

详细的构造分析与解析表明,渝东经历了晚元古代—古生代弱造山与稳定的克拉通盆地、中生代强造山与周缘前陆盆地、新生代造山后与残余盆地3个发育世代;现今构造格局与样式实为多期构造变形形迹的复合、联合与叠加。从总体上看,研究区纵向上可划分为3个构造层,其区域构造形态总体呈现前展式逆冲推覆薄皮构造样式,局部构造共见有7种变形样式。其中,下构造层主要发育双重构造与断弯褶皱;中构造层多发育断弯与断展褶皱;上构造层以形成滑脱、断展与突破构造为主;形成时代大致经历了晚燕山、早喜马拉雅、晚喜马拉雅三期;总体体现西冲的NE向逆冲构造体系形成期最早、东南方向逆冲的NEE向冲褶系形成期其次、东冲的NNE—近SN向逆冲褶皱系形成期最晚。研究区北部构造形成早于中南部,北端NWW—EW向逆冲褶皱系干扰、限制着中北部NE—NEE向逆冲推覆系向北延伸,中部发育的转换(调节)带区段具有比较明显的调节作用。

The typical tectonic morphology including submarine canyon,seamount,tectonic depression and tectonic platform has been described and analysed,based on the latest,high-precision multi-beam sounding data with full-coverage in the Okinawa Trough,as well as the three-dimensional submarine topographic maps.There are two kinds of tectonic morphologic features.One is approximately parallel to the axis of the Okinawa Trough and the other perpendicular to the axis.The mechanism of the formation of the tectonic morphology is inferred as: the collision between the Philippine plate and in turn,the Eurasian plate causes the backarc spreading and the tectonic morphology perpendicular to the axis of the Okinawa Trough,and in turn,the backarc spreading causes the linear seamounts and echelon tectonic depressions along the axis.The effects of plate collision together with backarc spreading created the above tectonic morphologic types in the middle and southern Okinawa Trough.Several key issues of tectonic researches in the Okinawa Trough are discussed: (1) The viewpoint of backarc spreading in the Okinawa Trough is supported by the evidences of tectonic morphology,multi-beam sounding data and seismic profiles and 3.5 kHz profiles from the Sino-French cruise in 1996,and the evidences of strong magnetic anomalies,high heat flow,strong volcanism,strong magmatism and frequent earthquakes.The directions,amount and rates of the tectonic movements with three stages are estimated quantitatively.(2) Several models of the tectonic evolution in the Okinawa Trough are summarized,and the evolution process of the Trench-Arc- Backarc basin system are discussed geodynamically.(3) The evolution of the tectonic movements with three stages in the Okinawa Trough is proposed based on the collected evidences,namely,the uplift and rift of Miocene,the passive extention from Pliocene to early Pleistocene,and active backarc spreading from late Pleistocene to Holocene.There are obvious differences among the directions,features and mechanism of the tectonic movements with three stages.The changes of extentions in the trough created the tectonic morphology with several kinds of strike,and recent spreading of the Okinawa Trough is becoming more active and faster.

在冲绳海槽区采用国内最新勘测的多波束数据构建高分辨率的DTM(DigitalTerrainModel),选择典型海区绘制了相应的三维海底形态图件,并在此图件基础上定量分析了冲绳海槽典型构造地貌形态:海底峡谷、海山、构造洼地和构造台地,统计分析表明冲绳海槽存在近似平行和近似垂直海槽轴向两种走向的构造地貌单元。对构造地貌的成因机制进行了推测,认为菲律宾板块和欧亚板块间的相互作用是产生与海槽走向垂直的构造形态和弧后扩张的动力源,而弧后扩张则产生了沿海槽走向分布的线性海山和雁行排列的构造洼地。在中部和南部海槽这两种作用力交织在一起,产生两类海底地貌形态共存的构造格局。对目前关于冲绳海槽构造研究的几个关键问题进行了探讨,阐述并支持了冲绳海槽弧后盆地扩张成因的观点;定量估算了冲绳海槽三幕构造运动的方向、扩张量和半速率;从动力学角度阐述了沟 弧 盆体系的形成演化过程;阐述了冲绳海槽三幕构造运动的演化过程和特征:中新世的拱顶、断陷,上新世—早更新世的被动拉张,晚更新世—全新世后的主动弧后扩张。三幕构造运动的方向、特征和动力机制明显不同,运动方向的多次改变导致海槽内多种走向构造地貌的存在。近代的海槽扩张有明显活跃和加速趋势。
