本文对毕家山铅锌矿床和围岩中可溶有机质进行了分析，研究了矿床中有机质的性质、来源和成熟度，进而探讨了矿床中有机质的原始运移形式、成矿溶液可能的成因以及矿床形成的环境。结果表明，矿床中有机质主要属水生生物和细菌成因，它起源于灰岩矿源层，其原始运移形式可能为腐殖酸；成矿溶液可能形成于成岩早期，来自灰岩矿源层；矿床形成于强还原环境。这些无疑对矿床成因的了解具有重要意义。
In this paper, the soluble organic matter in the Bijiashan Pb-Zn deposit and its surrounding rock was analyzed, and the nature, source and maturity of the organic matter in the deposit were studied. Then the original migration patterns of the organic matter in the deposit, the possible genesis of the ore-forming solution, Deposit formation environment. The results show that the organic matter in the deposit is mainly of aquatic organisms and bacteria, originating in the limestone source layer, and the original migration pattern may be humic acid. The ore-forming solution may be formed in the early diagenetic stage from the limestone source layer. Yuqiang restore the environment. These are undoubtedly the origin of the understanding of the deposit of great significance.
