To gain a comprehensive understanding of the electrical structure and geological structural characteristics of the Jingerquan region in eastern Tianshan, and to provide electrical evidence for its metallogenic mechanism, a magnetotelluric sounding profile was completed in the area. By utilizing three- dimensional inversion, a reliable electrical structure model was obtained. The results revealed the following insights: ① the shallow part of the Kangur- Huangshan ductile shear zone exhibits a thin layer of high conductivity. This suggests that the shallow surface rock layer may have undergone significant ductile shear deformation, leading to the presence of fractured and loose rock, potentially accompanied by fluids; ② the Yamansu fault serves as a channel for fluid transport to greater depths, causing the fractures below it to exhibit high conductivity anomalies; ③ the mineralization model of the Hulu copper- nickel sulfide deposit is consistent with the magma channel mineralization model. The Kangur Fault serves as a pathway for the upward intrusion of mantle- derived magma. During this process, the magma carries copper- nickel sulfides, which subsequently undergo gravitational subsidence and aggregate mineralization at bends in the channel, magma chambers, or dilation sites. Additionally, it is speculated that there may be sulfide- rich basic rocks at a depth of 2 km, suggesting the potential for Cu- Ni metallogenic at that depth.
