Abstract According to the geological structure evolution characteristics of the polymetallic metallogenic belt, the key to solve the problem of mineral resources shortage is to analyze the dominant deposit types, metallogenic mechanism, and metallogenic process of the polymetallic metallogenic belt. On this basis, the analysis method of geological structure evolution characteristics of polymetallic metallogenic belt is put forward. Taking the Wuyishan polymetallic metallogenic belt as the research object, the comprehensive investigation methods of 2D seismic exploration, drilling, geophysical logging, and sampling test are used to control the structural morphology and polymetallic in Wuyishan area. Through drilling, logging, and laboratory tests, the occurrence range, buried depth, thickness, and structure of the polymetallic metallogenic belt are controlled. According to the evaluation results of mineral resources potential in China, it is proposed that the main mineral exploration directions of Wuyishan polymetallic metallogenic belt are rare earth, fluorite, copper-molybdenum, lead-zinc, tin, gold, and silver. The main types of ore deposits include weathering crust-type (ion adsorption type) rare earth deposit, porphyry copper-molybdenum gold deposit, and sedimentary reformed lead-zinc polymetallic deposit. Hydrothermal fluorite deposit and hydrothermal w-sn-bi-mo-ta deposit related to acid rocks are delineated, and eight key prospecting areas in the metallogenic belt are delineated.

Introduction With the development of the times, the global resources are becoming more and more scarce, and mineral resources are also receiving more and more threats (Chen et al. 2017b, Liu 2017, Zong et al. 2018). The study of prospecting measures has become one of the most important tasks in the world. The metallogenic model and metallogenic prediction also need to be studied and improved in order to promote the exploration of ore deposits (Chen et al. 2016; Zhang et al. 2017). Metallogenic zone/belt, synonymous with metallogenic zone, refers to the area with commonness in geological structure, geological development history, metallogenic process, and ore deposit characteristics (Li et al. 2016).

are generally characterized by narrow strips, and ore-forming areas with similar aspect ratios are called ore-forming areas. According to the further division of geotectonics and metallogenic characteristics, the metallogenic belt (area) can be divided into first (metallogenic domain), second
