crystalline basement

The early Mesozoic thrust nappe structure in western Fujian is composed of three basic tectonic units: the crystalline basement obduction zone in the central part and the cover fold thrust zone in the east.

闽西地区的早中生代逆冲推覆构造由3个基本构造单元组成：西部结晶基底仰冲带、中部活化基底剪切滑脱带和东部盖层褶皱冲断带。

The upper crust of the Altun orogenic belt has a high average Q value ( about 500). It is likely caused by shallow depth of crystalline basement, outcrop of basement rocks, and slow attenuation of seismic wave.

阿尔金造山带上地壳的平均Q值较高（约500），这可能由于结晶基底埋藏较浅，基岩出露，因此地震波在此处传播能量衰减较慢所致。

The final model indicates that the thickness of the main part of Tarim basin varies in the range of 38~ 46 km. The model also reveals that the Moho dips southward beneath southern Tarim basin at an angle in concordance with the angle of the crystalline basement.

最终的模型显示塔里木盆地主体的地壳厚度为38～46km，而且塔里木南缘的Moho界面南倾，与结晶基底南倾的角度大体一致。
