摘　　要：本文以云南会泽铅锌矿床为例 ,从成矿时代、成矿物来源、成矿流体来源和成矿热动力等方面初步讨论峨眉山玄武岩与铅锌矿床成矿的关系。结果表明 :矿床成矿时代可能与峨眉山玄武岩岩浆活动时代相近 ;峨眉山玄武岩在成矿过程中提供了部分成矿物质 ;伴随峨眉山玄武岩岩浆活动过程去气作用 (包括地幔去气作用和岩浆去气作用 )形成的流体参与了会泽铅锌矿床成矿流体的形成 ;峨眉山玄武岩岩浆活动为成矿热动力的主要来源。Taking the Huize Pb Zn deposit as an example, this paper deals with the genetic relationship between Emeishan basalt and Pb Zn deposits in terms of ore forming age, ore forming material source, ore forming fluid source and metallogeno thermal dynamics. The results show that the mtallogenic age of the Huize Pb Zn deposit seems to be close to the age of formation of Emeishan basalts, the basalts may have provided ore forming materials, the fluid resultant from degassing (including mantle degassing and magmatic degassing) in accompany with the Emeishan basaltic magmatic activities was involved in the formation of ore forming fluid responsible for the Pb Zn deposits, and the Emeishan basaltic magmatic activities are the main source of metallogeno thermal dynamics.
