厂坝铅锌矿床矿体为层状，具有韵律性沉积层序，矿体内发育喷气沉积岩，并且在矿体下盘发育特征的网脉状矿化蚀变带，在矿体外围有富阳起石蚀变岩。这些地质特征充分说明矿床由喷气沉积作用形成。矿床的微量元素、稀土元素及硫、碳－氧和铅等稳定同位素特征表明矿床的硫和碳来源于古海水，成矿金属来源于矿体下伏地层柱。据此，提出了厂坝超大型矿床的形成机制。
The ore body of Changba lead-zinc deposit is stratified, with rhythmic sedimentary sequence, jet sedimentary rocks developed in the ore body, and characterized by reticular mineralized alteration belt in the footwall of the ore body. There are Fuyang rock Rock alteration. These geological features fully demonstrate that the deposit is formed by jet deposition. The stable isotopes of trace elements, rare earth elements, sulfur, carbon-oxygen and lead in the deposit indicate that the sulfur and carbon in the deposit originated from the ancient seawater, and the metallogenic metals come from the underlying stratigraphic column of the ore body. Based on this, the formation mechanism of the ultra-large deposit in the dam is proposed.
