Structural pattern of the Maigaiti Slope in the Tarim Basin

The Maigaiti Slope is a secondary structural unit in the Tarim Basin, which underwent multiple tectonic movements. The stacking of structural deformation was controlled by basement structures or faults, multiple tectonic movements, stress field transition and regional detachment levels. According to the structural origin, the structural pattern in the study area can be divided into compressional, strike-slip, salt-related and magmatic structure, and each of them can be subdivided into several subtypes. The multiple tectonic movements led to the transformation of pre-existing structures and the formation of new structures. Various tectonic patterns were observed, including basement faults-increasing gypsum salt bed-back thrust, pre-existing uplift-draping anticline, pop-up block hill-draping anticline, magma diapir-draping anticline, basement-involved fault-synthetic/antithetic cap rock detachment, strike-slip fault-shallow detachment, and imbricate structure.
