The Mushi anticline locates at the frontier Pamir arcuate nappe tectonics belt (PFT), which is a detachment fold with a gentle south limb and steep north limb, and its earth crustminimum shortening is ～0.7 km with uplift up to 1.5 km.The north limb fault of Mushi anticline is composed of a series of obsequent slope fault scarps, and the distribution of vertical displacements among different fault scarps presents a pattern of one increasing and the other decreasing. No matter of the entire western segment of the northern limb faults or a single fault, the displacement distribution is asymmetric, that is, high in the east and low in the west, and the same to displacement gradient. This may reflect the Late Quaternary folding of Mushi anticline as being intensive in the east and feeble in the west. The fault may be a shallow, rootless secondary fault formed during the growth process of the anticline in order to accommodate the constantly decreased space of anticline nucleus as the fold tightened gradually.
