According to the ground geological, geophysical and drilling data, characteristics of distributions and section structures of Maxian fault belt in northern Qaidam Basin are analysed. Its formation and development time and kinematic characteristics are detailed researched. On the basis, a reasonable kinematics model of the active fault is proposed. The results are that Maxian fault is formed in Late Cretaceous, and has a long-term activity in Cenozoic, controlling basin structures, sedimentary distributions and oil and gas accumulations, The fault dips to south and is a left-lateral strike-slip thrusting fault. The kinematic characteristics of Maxian fault derive from the differential pushes of south Qilian Mountains to Qaidam Basin. Source
