摘要
The Bafangshan-Erlihe Pb-Zn (Cu) deposit is located in the northwest of the Fengxian-Taibai (Fengtai in short) ore concentration area, West Qingling. This paper studies in detail its ore-forming characteristics, and divides the ore-forming process into three stages: the early stage sphalerate-rich sulfide, middle stage quarz-polymetallic sulfide, and the late stage quarz-carbonate based on the mineral combination of the ores, textures and structures, wall rock alteration, and the interpenetrating relationships of the ore veins. Integrated with previous research results about the mineralization epoch, structural styles and evolution, magmatism, it is suggested that the Bafangshan-Erlihe Pb-Zn (Cu) deposit is the product of the regional tectono-magmatic-mineralization processes, and it is an epigenetic deposit formed by hydrothermal filling and metasomatism. This insight would provide enlightenment for understanding the deposits which have similar ore-forming characters to the Bafangshan-Erlihe Pb-Zn (Cu) deposit in the Fengtai ore concentration area, West Qinling.
