本文以湖南花垣铅锌矿床和贵州牛角塘铅锌矿床为例，探讨了湘西黔东地区铅锌矿与古油藏的关系。二者在空间分布上关系密切，存在“共生”和“上油下矿”两种关系，下寒武统清虚洞组既是铅锌矿重要的赋矿层位也是古油藏储集层之一；铅锌矿源层可能为新元古代基底岩系或下寒武统石牌组碎屑岩，古油藏烃源岩主要为下寒武统牛蹄塘组。古油藏中的油田卤水萃取了石牌组碎屑岩中的铅锌等成矿物质，形成成矿流体并运移，在古油藏形成后，由于加里东末期的构造运动的影响，古油藏和成矿流体的平衡被打破导致铅锌矿质沉淀，在这个过程中古油藏中的油田卤水可能为铅锌矿的沉淀提供了部分硫源。铅锌矿成矿时代与加里东期形成或破坏的古油藏时间上较为一致。

We take Huayuan Pb-Zn deposit in Hunan Province and Niujiaotang Pb-Zn deposit in Guizhou Province as examples to discuss the relationship between Pb-Zn deposits and paleo-oil reservoirs in western Hunan and eastern Guizhou Province. Both are closely correlated with each other of spatial distribution and there exists two relationships which are "paragensis" and "above oil beneath ore deposit". The Lower Cambrian Qingxudong Formation is both the important ore-bearing strata of Pb-Zn deposits and one of the paleo-oil reservoirs. The probable lead-zinc source beds are Neo-proterozoic basement rocks or Lower Cambrian Shipai Formation clastic rocks, while the main source rock of paleo-oil reservoir is Lower Cambrian Niutitang Formation. Oilfield brine extracted the ore-forming materials from the Lower Cambrian Shipai Formation clastic rocks and carried them to migrate. Influenced by Caledonian Movement, the balance of paleo-oil and Ore-forming fluid was destroyed, which attributed to the precipitation of Pb-Zn deposit, and in this process the oilfield brine of the paleo-oil reservoir probably provided Pb-Zn deposits with ore-forming sulfur. The Ore-forming time of Pb-Zn deposits is nearly the same as that of the accumulation and destruction of the paleo-oil reservoir during Caledonian.
