A deep sounding work by converted waves of earthquakes has been conducted in Xingtaiearthquake region. As a result, 6 cross-sections of deep structure in Xingtai earthquake area havebeen constructed (3 in NW trend and others in NE trend). On the bases of these sections thestructures of major deep crustal interfaces G,C and M were determined. At the same time, thevelocity models of P and S waves were constructed. Moreover, background of 3-D deep structureand the dynamic conditions for earthquake occurrence are...

在邢台地震区开展了地震转换波测深工作,得出了6条深部构造剖面图,其中包括3条NW向和3条NE向剖面,同时也得出了地壳内G、C和M3个主要深部界面的埋深分布图以及地壳内波速分布模型。在此基础上讨论了邢台强震发生的深部三维构造背景和深部孕震条件。

A deep-sounding observations by using the PS converted waves of the earthquakes along the rmqi-Korla profile across the Tianshan mountains have been conducted with the cooperation efforts of Chinese, Kazakhstan and Kirghizstan scientists in 1992. As a results a cross-ection of deep crust structures and the velocity models of P and S waves along the profile were obtained. The consolidate crust of the Tianshan mountains is consisted of 4 layers with the velocities of Vp=5.9km/s, 6.3km/s, 6.6km/s, 6.9km/s, Vs=3.2km/s,...

As a results a cross-ection of deep crust structures and the velocity models of P and S waves along the profile were obtained. The consolidate crust of the Tianshan mountains is consisted of 4 layers with the velocities of Vp=5.9km/s, 6.3km/s, 6.6km/s, 6.9km/s, Vs=3.2km/s, 3.5km/s, 3.7km/s, 3.9km/s. The velocities of the top of the upper mantle are: Vp = 8.1km/s and Vs=4.6km/s. The thickness of the crust is ranging between 42km and 56km. The maximum thickness of the crust in middle Tianshan reaching to 53-56km. There are some low-velocity lens in the middle part of the crust. The results show that the Tianshan mountains are divided into three tectonic zones: northern, central and southern Tianshan, different in the characteristics of the deep crustal structures, and it seems that the formation and the evolution of the Tianshan mountains can be explained with the theory of Surge Tectonics-a new hypothesis of Earth dynamics more resonably then the theory of Plate Tectonics.

沿乌鲁木齐-库尔勒350余公里长的测线上完成了穿越天山的地震转换波野外观测,得出天山造山带的深部构造剖面图和壳内P,S波速度结构模型.天山的结晶地壳可分为4层,各层的速度分别是:Vp值为5.9,6.3,6.6,6.9km/s;Vs值为3.2,3.5,3.7,3.9km/s。上地幔顶部的波速:Vp值为8.10km/s。Vs值为4.6km/s。天山地区的地壳厚度为42-56km,中天山最厚,达到50-56km。地壳中部存在低速透镜体。探测结果表明,天山大地构造可分为北天山、中天山和南天山3个区,其地壳深部构造特征各不相同。用颤动构造理论来解释天山造山带的形成机制和演化较板块构造理论更为合理。

The characteristics of deep structure are researched by using natural converted wave on Urumqi —Kuerle Profile in Tianshan area. The studying result shows: There are five obvious velocity interfaces including Moho,and they are cut by several faults,thus being divided into five structural units; The interface in the middle of Tianshan has lifted in different extents,forming thrust faults. Howerer,the crustal thickness at this area is less than that at its both sides of south and north,that shows the lifting of...

The characteristics of deep structure are researched by using natural converted wave on Urumqi —Kuerle Profile in Tianshan area. The studying result shows: There are five obvious velocity interfaces including Moho,and they are cut by several faults,thus being divided into five structural units; The interface in the middle of Tianshan has lifted in different extents,forming thrust faults. Howerer,the crustal thickness at this area is less than that at its both sides of south and north,that shows the lifting of mantle material possibly increases the average density of crust; At the area of Hejing and Baluntai on southern edge of the Tianshan,the faults are complicated,and the interfaces deform severely,so this is an area where tectonic activity is relatively strong in future.

利用天然地震转换波研究了天山地区乌鲁木齐─库尔勒剖面的深部构造特征。地壳中存在5个较明显的速度界面(包括莫霍面),并被数条断裂切割,相应地分为5个构造单元;天山中部的界面均有不同程度的抬升,在地壳中形成逆冲断裂,而地壳的厚度小于南北两侧地区,表明地幔的物质向上隆起,有可能造成地壳平均密度增加;天山南缘的和静、巴伦台一带断裂错综复杂,界面严重变形,是未来构造活动比较强烈的地区。
