Abstract:

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.

Key words: Kuqa foreland basin, physical modeling, salt structure, Qiulitake
