宁蒗地区白牛厂铅锌矿区位于区域性牛窝子－罗卜地帚状构造的内旋断裂带－白牛厂弧形断裂的折拐部位。该部位喜马拉雅晚期隐伏合矿斑岩体发育，其围岩地层一下二叠统（P1x）灰岩亦具一定的含矿性。由白牛厂弧形断裂伴生的低级次日牛厂帚状断裂构造带又为本区矿液运移和矿体赋存提供了良好通道和有利空间。在白牛厂隐伏斑岩体与共围岩（P1x灰岩）的外接触带、构造叠合地段，有望形成斑岩体外接触带热浪型铅锌（银）多金属矿床。
The Bai Niu lead-zinc mine in Ninglang area is located at the turning point of the arc-shaped rupture of the Bai Niu plant in the regional bovine rover-broom structure. In the area, the late Himalayan ore-bearing porphyry of the Himalayas developed and the Permian (P1x) limestone in the surrounding rock strata also has some ore-bearing properties. The low-grade bovine rupture tectonic belt associated with the arc-shaped rupture of the White Cattle Plant also provided a good channel and favorable space for the migration of ore fluids and the occurrence of ore bodies in this area. In the outer contact zone of the Bai Niu buried volcanic porphyry and the common rock (P1x limestone), the superimposed area is expected to form a Pb-Zn (silver) polymetallic deposit with heat-wave type in the in-vitro contact zone of porphyry.
