同位素资料表明，可可塔勒铅锌矿床成矿时代为早泥盆世，与下泥盆统海相火山岩系年代一致；矿石铅主要来自于活动造山带，与弧盆系火山岩有关，属幔壳混合铅；矿石的硫源与赋矿围岩或后期脉状矿石的硫源存在明显的差异，前者属细菌成因硫和海水硫酸盐还原硫的混合，后者属深部火山硫或岩浆硫；主成矿期的成矿介质水主要是海水，可能有少量大气降水加入，后期矿化则以混合岩浆水为主。矿床形成属海底火山喷气－沉积迭加改造型矿床。
The isotopic data indicate that the mineralization age of the cocoa Tale lead-zinc deposit is Early Devonian and consistent with the age of the Lower Devonian marine volcanic rocks. Lead in the ore is mainly derived from active orogenic belts and is related to the volcanic rocks in the arc basin. Mixed lead; there is a clear difference between the sulfur source of the ore and the sulfur source of the ore-bearing rock or late vein ore. The former is a mixture of sulfate-sulfur and seawater sulfate-reduced sulfur, the latter is deep volcanic sulfur or magmatic sulfur. The metallogenic water in the mineralization stage is mainly seawater, may have a small amount of atmospheric precipitation to join, late mineralization is mainly mixed magmatic water. The deposit is formed by submarine volcanic-sedimentary superimposed alteration deposit.
