金顶铅锌矿位于兰坪盆地中部，控矿构造为金顶逆冲推覆构造。流体包裹体及硫同位素研究表明：矿区中的硫属于正常沉积系统，并具有有机生物成因的特点；成矿流体均一温度72.9～490℃，盐度为7.4％～16.9％，成矿压力85～230 MPa，成矿流体pH值5.36～7.09，Eh值为-0.44～1.17 V。矿床形成于新生代陆内汇聚构造背景，？江断裂的长期活动与输送含矿物质热卤水，贯入到金顶穹隆构造，形成“金顶式”Pb-Zn矿床。

Jinding lead-zinc deposit is located in the middle of Lanping Basin in Yunnan Province,and its ore controlling structure is Jinding thrust nappe.The fluid inclusions and sulfur isotope studies show that sulfur of the deposit belongs to normal sedimentary system and shares characteristics of bioorganic process;homogeniza-tion temperature of ore-forming fluid is 72.9 to 490 ℃;salinity is 7.4%to 16.9%;mineralization pressure is 85 to 230 MPa;ore-forming fluid pH is 5.36 to 7.09;Eh value is -0.44 to 1.17 V.The deposit formed in Cenozoic intracontinental tectonic activities.Long-term activities of Bijiang River fault and mineral hot brine, injecting into Jinding vaulting,result in the forming of Jinding lead-zinc deposit.
