The study constructs the 3-D framework of the S-shaped Huangshi strike-slip structure. The Huangshi structure is a positive flower or Y-shaped structure in seismic sections. Surface fractures at the core of the Huangshi structure are in Riedel shear pattern. The secondary Hongpan and Xiaoshaping structures are thrust-controlled anticlines. Two conjugate strike-slip fracture sets occur at the surface of the Hongpan structure.
