摘　　要：基性岩对卡林型金矿成矿起着至关重要的作用,不仅为其提供物质来源还提供形成所需的环境。早期基性岩为卡林型金矿提供环境,晚期基性岩提供成矿物质。本文主要针对云南富宁者桑金矿的早晚两期基性岩的岩石学、锆石U-Pb年代学进行研究,并与利用年代学来探讨两期基性岩的源区特征和成因机制,分析两期基性岩对金矿化的影响,建立该区卡林型金矿的成矿模式。Basic rocks play an important role in the mineralization of Carlin type gold deposits, not only providing material sources but also providing the necessary environment for their formation. The early basic rocks provide the environment for Carlin type gold deposits, while the late basic rocks provide the minerals. This paper mainly studies the petrology and zircon U-Pb chronology of the early and late basic rocks of Zhesang gold deposit in Funing, Yunnan, and discusses the source characteristics and genetic mechanism of the two basic rocks by using chronology, analyzes the impact of the two basic rocks on gold mineralization, and establishes the metallogenic model of the Carlin type gold deposit in this area.
