黔西南三道沟金矿与峨眉山玄武岩成矿关系初探 摘要 黔西南三道沟金矿与峨眉山玄武岩成矿关系是一个重要的研究方 向，本文通过对三道沟金矿和峨眉山玄武岩地质、地球化学特征的综合 分析，初步探讨了二者之间的成矿关系。研究表明，三道沟金矿位于峨 眉山玄武岩地体边缘位置，冲蚀堆积层中发育有较多的金矿化旋回，显 - 示出明显的岩浆热液成矿特征，表明三道沟金矿是峨眉山玄武岩岩浆作 用的产物。本文的初步探索对于进一步深入研究黔西南地区的金矿成矿 规律和峨眉山玄武岩成矿机理具有现实意义。 关键词：黔西南；三道沟金矿；峨眉山玄武岩；成矿关系 Abstract The relationship between San Da Gou gold deposit in southwestern Guizhou and Emeishan basalt is an important research direction. Through the comprehensive analysis of the geological and geochemical characteristics of the San Da Gou gold deposit and the Emeishan basalt, this paper discusses the mineralization relationship between them. The study shows that San Da Gou gold deposit is located near the edge of the Emeishan basalt and there are many gold mineralization cycles in the erosion and accumulation layer, which shows obvious magmatic-hydrothermal mineralization characteristics, indicating that San Da Gou gold deposit is aproduct of Emeishan basalt magmatic activity. This paper's preliminary exploration has practical significance for further research on the mineralization laws of gold deposits in southwestern Guizhou and the mineralization mechanism of Emeishan basalt.
