通过埋藏史、构造沉降史恢复以及以破裂弹性薄板末端单点负载挠曲为模型对库车中新生代前陆盆地的宽度、前缘隆起和造山带高度、岩石圈性质的模拟计算 ,综合前人研究成果表明 :(1)三叠 -侏罗纪、早白垩世的原始沉积展布呈北东向 ;(2 )构造沉降曲线在北部呈陡 缓 陡的 3段式 ,往南渐变为缓 陡 缓 陡的 4段式 ,并均具上凸的特点 ;(3)盆地演化早期 (P2 -T)和晚期 (N -Q)的横向沉积结构呈典型前陆盆地的楔状几何形态 ,演化中期 (J-E)则呈不对称的“V”字形几何形态。
Based on the burial history, the restoration of tectonic subsidence history and the single-point load deflection at the end of cracked elastic sheet, the simulation of the width, frontal uplift and orogen height and lithosphere properties of the Cenozoic foreland basin in Kuche is conducted. The results of the study show that: (1) Triassic-Jurassic, Early Cretaceous primary sedimentary distribution is northeast; (2) tectonic subsidence curve is steep and steep 3 sections in the north, Steep and steep 4-stage, and all of them are convex. (3) The horizontal sedimentary structure of the early evolution (P2-T) and late (N-Q) of the basin shows the wedge geometry of the typical foreland basin, (JE) is asymmetric “V” shaped geometry.
