///Based on reconnaissance survey and geological mapping as well as comprehensive literature review and laboratory study, this paper presents the following conclusions： 1) the Jiama-Kajunguo thrust-gliding nappe tectonic system, which resulted from the Indo-Asia collision; 2) the footwall block of the nappe is the Yeba Group tectonite, the nappe consists of the upper Jurassic and lower Cretaceous carbonate and siliciclastics, the main part that is a complex fold with axial plane trends northward and can be divided into the fore-, mid- and post-parts from south to north structurally; and 3) the magmatic activities that induced the ore-forming alteration of the Jiama（Gyama） deposit happened during the releasing stage after the contraction stage of the thrust-gliding nappe tectonic system, and the upward migration of the magma was collaboratively controlled by the NS-trending basement faults and the thrusts.
