查询词典 tectonic

The study of ore-forming rules indicates that the shearing force came from interaction of plate-plate is the initial force, which result in remelting of deep rock. Early formed faults and later dome structures provide favourable passage-way for ore-material migrating. Finally due to complete circulate convection, ore-material experience a process of complete differentation and begin to crystal and settle in certain circumstance. In some favourable tectonic zone ore-forming material enriched to deposit.

对成矿机制的研究显示板块作用产生的剪切力是造成区内深部岩石重熔的源动力，而早期形成的断裂体系及后期形成穹窿构造为矿物质的运移提供了有利的通道，在完善的循环对流机制配合下，成矿物质在迁移过程中发生较为充分的分异作用，各类矿物质在相应的物化环境中结晶沉淀，并在有利的构造部位富集成矿。

In order to find new pegmatite Nb-Ta ore-deposit, it is very important practical-significances to ascertain the host structure characteristics and the relations between the tectonic epochs and ore-forming.

通过查明矿床的容矿构造特征以及构造期次与成矿的关系，对寻找新的铌钽伟晶岩矿床具有重要的实践意义。

The protolith of northern khondalite series in neighbouring region is a suite of flyschoid formation consisting of argillaceous arkose-pelitic feldspathic greywaske with intercalations of pelite, silt as well as carbonate and marl beds. They were deposited on continental margin under relative stable tectonic enviroment.

所有特征表明二者之间不存在有些研究者所认为的不整合接触关系，而是大量奥长花岗质-英云闪长质和一些中基性岩浆顺层侵入到一套沉积和火山-沉积表壳岩中，并一起经受多期复杂的变质和变形作用所成。

These planation surfaces are comparable with the summit planation surfaces of the mountains on the Tibetan Plateau and in the Beitai episode in Northern China, probably implying that they were united peneplain during the end of the Oligocene Epoch, although they are far from each other and are even located in different plates and tectonic systems.

说明中国大陆各部虽相距遥远，甚至处于不同的板块和构造休系，但在渐新世末却处于统一的准平原状态，大范围长尺度造山运动的脉搏似乎是一致的。

The tectonic evolution history of Tianshan is an example. In the Triassic, it was once uplifted to form the mountains with thick molasse accumulation on both its sides, Junggar and Tarim Basins. Then it became a peneplain by the exposion and deplanation in the Jurassic, forming the widespread coal-bearing strata which can be correlated. From the Cretaceous to the Early Cenozoic, it was uplifted again, until the Quaternary to build huge mountains with two large sedimentary basins on both sides.

如天山山脉的构造演化，三叠纪天山曾经一度隆起成山，两侧的准噶尔和塔里木盆地中堆积了巨厚的磨拉石；侏罗纪时由於剥蚀夷平成为一个准平原，形成了广泛分布且可以对比的含煤岩系；从白垩纪到早新生代，它再度隆升，直至第四纪时形成雄伟的高大山系，两侧形成相应的大型沈积盆地。

In Jurassic-Paleogene, the West Kunlun, West Tianshan, Tarim and the Central Asia exhibited a relatively quiet period after the orogenic movement. Due to extension, these area displayed peneplain tectonic geomorphologic landscape.

侏罗纪，西昆仑、西天山、塔里木大陆及中亚—带都处于造山期后的相对宁静期，以仲展构造作用为主，主要表现为准平原化的构造地貌景观，沉积有高成熟度的侏罗纪含煤岩系，塔西南表现为陆内伸展盆地，这一时期可持续到早第三纪。

The tectonic evolution of southern Junggar basin can be classified into seven stages: stage of intracontinental rift from middle Periman to late Late Carboniferous; stage of weak extension and peneplane from late Permian to early Triassic; stable depression stage in middle-late Triassic; maximal basin formation phase in the setting of weak extension in early-middle Jurassic; inactive depressed basin formation phase in thrust setting in middle-late Jurassic; stable depression stage in Cretaceous and Eogene; foreland depressed basin formation phase in thrust setting in Neocene and Quaternary.

准噶尔盆地南缘晚石炭世以来盆地构造演化可划分为七个演化阶段：晚石炭世—中二叠世陆内裂谷作用阶段；晚二叠世到早三叠世处于弱伸展-稳定坳陷作用阶段；中、晚三叠世准平原化作用阶段；早、中侏罗世为弱伸展背景下广盆形成阶段；中、晚侏罗世冲断背景下的坳陷盆地形成阶段；白垩纪到古近纪弱伸展背景下的稳定坳陷盆地形成阶段；新近纪—第四纪为冲断背景下的前陆坳陷盆地形成阶段。

The research results imply that the regional tectonic stress field has resulted in deformation and flow of upper mantle material with clockwise rotation,and make the alignment of upper mantle peridotite lattice parallel to the direction of material deformation. The deformation of the crust and upper mantle is possibly vertically coherent deformation.

研究表明青藏高原东北缘上地幔物质在区域构造应力场的作用下，发生了顺时针旋转的形变以至流动，使得上地幔中橄榄岩的晶格排列方向平行于物质形变或流动方向，上地幔变形和上覆地壳变形可能存在垂直连贯变形特征。

A similar tectonic style is evidenced for the Permian Basin as a whole.

类似的构造样式是休戚相关的二叠纪盆作为一个整体。

The study of ferrogabbro and its petrogenesis will play an important role in studying tectonic setting and dynamic background, deep process of the Beijing area during Yanshanian Movement.
