长坑金银矿床是近年来国内发现的矿床新类型，金、银既共生于同一矿床中又分别构成独立矿体；金、银矿体在硫、铅同位素组成方面存在明显差异，金矿体铅同位素组成与围岩铅相似，表明金、银在成矿物质来源或成矿过程方面存在差异。
The Changkeng gold-silver deposit is a new type of deposit discovered in China in recent years. Both gold and silver are intergrowth in the same deposit and form independent ore body respectively. The gold and silver ore bodies have obvious difference in sulfur and lead isotopic composition. The Pb isotopic composition is similar to that of the surrounding rock, indicating that gold and silver differ in the source of mineralization or the metallogenic process.
