Abstract:The Meixian Pb-Zn-Mo polymetallic deposit in central Fujian is an important part of the Wuyishan metallogenic belt. Combined with the geological work recently carried out in the mining area, this paper expounds the ore body characteristics and ore characteristics of the deposit in Meixian mining area. The lead-zinc ore body is distributed in layers and quasi layers, and the ore is mainly in massive, banded and laminated structures; The shape of molybdenum ore body is often affected by fractures and rock mass, the ore is mainly in membrane structure, network vein structure, vein fine vein structure and thin layer structure. Based on field observations and laboratory studies under a microscope, combined with previous research results, it is believed that the lead-zinc-molybdenum polymetallic ore-system massive sulfide deposit in the mining area is a product of the coupling and superposition of the porphyry metallogenic system. The mineralization age can be roughly divided into three stages: (1) Initial volcanic eruption-syngenetic sedimentation and mineralization stage; (2) Regional metamorphism and mineralization stage; (3) Magmatic hydrothermal superposition-transformation mineralization stage. And a possible metallogenic model is established according to these three stages. The resulting metallogenic model has been verified by recent exploration work.
