Mylonitic coal may develop in the center of strongly deformational belt in pressing tectonic stress field. Since mylonitic coal is limited in a narrow area, biggish area in that tectonic coals of brittle deformation distribute is favorable for CBM exploration. Moat of areas are advantageous for formation of coalbed fractures and increase of permeability in extension stress field, but it is easy to beget dissipation of CBM and decrease of gas content. Therefore, study of structure of gas reservoir should be taken seriously.

研究表明，挤压应力场作用下，在强变形带的中心及其附近，可以形成糜棱煤类构造煤，但糜棱煤分布较为局限；在较大范围内形成脆性变形系列的构造煤，是煤层气勘采的有利区带；拉张构造应力场中，大部分区域内有利于煤层裂隙的形成和渗透率的提高，但易造成煤层气的散失，含气量降低，应重视有利的储气构造的研究。

According to deformation mechanism, sytectonic paragenetic association of minerals and deformation environment, metamorphic tectonites are divided into tectonic gneiss series, tectonic schists series and mylonitic series.

依据变形机制、组构、同构造新生矿物组合，以及形成环境，将韧性剪切带中变质构造岩分为构造片麻岩系列、构造片岩系列和糜棱岩系列。

Among above deformation, the thrust-fold structure formed in Triassic established the E-W trend framework controlling the distribution of the late compressive settling. The NNE-NE trend obduction zone and regional folds is contributed to effect of Tethys tectonic region superimposed by Paleo-Pacific tectonic region.

其中三叠纪挤压变形产生的冲断—褶皱构造，奠定了本区中生代近东西向构造格局，并控制后期挤压坳陷型盆地的的空间展布规律；晚侏罗世早期挤压形成的北北东—北东向逆冲推覆构造带和区域性褶皱是特提斯构造域与古太平洋构造域共同叠加的结果。

The author has paid attention to the two kinds of lavas which locate the south-east end of the Kalamaili belt. Through the field investigate and the geochemistry experiment the author has contrasted the two kinds of lavas in the ophiolitic melange, made clear the tectonic background and summarized the geochemical characteristic and then discussed the formed environment and tectonic significance.

作者以该蛇绿混杂岩中的两类中基性火山熔岩为研究对象，通过野外实际观察和室内地球化学实验分析，将这两类火山熔岩进行对比研究，弄清其大地构造背景，总结其地球化学特征，并由此探讨该蛇绿混杂岩的形成环境及其构造学意义。

In the Tertiary, mountain frontal molasses deposited between the Yarlung Zangbo ophiolitic melanges and the Gangdese granitic batholiths, and the suture zone together with adjacent tectonic units were modified by thrusting and extension to the present tectonic configuration.

在雅鲁藏布蛇绿混杂带和冈底斯岩浆弧的前缘之间形成了山前磨拉石建造，缝合带及相邻构造单元被后期冲断层和伸展作用改造成现在的构造面貌。

This orogenetic process is a series of completed tectonic evolution, reflecting the initial orogenic magma underplating and magma mixing, the peak orogenic strong interaction between the crust and mantle, the late orogenic lithosphere started to delaminate and the post—orogenic extensional tectonic setting.

该造山过程为一套完整的演化序列，反映了初始造山的岩浆底侵作用，峰期造山强烈的壳幔相互作用，后期造山岩石圈开始拆沉作用及后造山的伸展构造背景。

The result of the basin's tectonic differentiation and the development of the salt-bearing strata indicate that in Palaeogene ang Neogene, the Kuqa basin had already had the tectonic environment in which the potash evaporite formed.

从盆地的构造分异结果及其控制的含盐系和其中石盐岩的发育特征来看，古近纪和新近纪库车盆地已具备钾盐蒸发岩形成的构造条件。

It stably subsided after its formation. During Palaeogene ang Neogene salt-forming, Kuqa basin experienced strong-weak-strong tectonic stages, and its center of subsidence moved gradually from north to south and depocenter from northwest to east and southeast. Because of tectonic differentiation, series of second depression formed in Kuqa basin.

盆地自形成以来一直处于稳定的沉降状态，在古近纪和新近纪成盐期，盆地经历了强-弱-强3个构造演化阶段，其沉降中心由北而南逐渐迁移，沉积中心由北西逐渐向东、南东方向迁移，盆地内的构造分异渐趋明显，形成了一系列次级凹陷。
