库车前陆盆地新生代盐构造特征及形成机制：物理模拟和讨论

膏盐层的存在对库车前陆盆地构造变形与演化具有重要的影响，导致了盐上构造与盐下构造形态的明显不同。盐上 构造以宽缓的褶皱为主，而盐下构造则以紧密排列的冲断层为主。我们采用构造物理模拟方法对库车盐构造变形演化过程 和变形机制进行了分析。研究表明，库车盐构造变形主要受区域挤压和同构造沉积作用的影响。在克拉苏构造带，盐构造 形成、演化的主控因素为区域挤压作用，而在构造带前缘的秋里塔格构造带，盐构造的主控因素则为邻区拜城凹陷的巨厚 同构造沉积。

Characteristics and Mechanics of Cenozoic Salt-Related Structures in Kuqa Foreland Basins: Insights from Physical Modeling and Discussion

Salt layer has a significant influence on the structural deformation and evolution of Kuqa foreland basin. Structural
styles are quite different in the strata beneath and above salt. Strata above salt are mainly deformed by broad folding, while strata
beneath salt are mostly deformed by closely-spaced thrusts. Based on scaled physical experiments, we investigate the deformation
pattern and mechanics of Kuqa salt-related structures. Modeling results show that Kuqa salt-related structures are primarily
controlled by regional compression and growth sedimentation. Salt structures near the back end, such as Kelasu fold belt, are
controlled by regional compression, and salt structures near the front end, such as Qiulitake fold belt, have a significant influence
from the heavy growth sedimentation in the nearby Baicheng syncline.
