Abstract Qingchengzi ore concentration area is located in the northern margin of North China Block and the central segment of Liaodong Rift Belt, and contains a great many medium and large ore deposits of lead-zinc, gold, and silver. In order to deeply understand the spatial distribution differences of lead-zinc, gold, and silver ore deposits in the ore concentration area and the migration direction of ore-forming hydrothermal fluids, the authors summarized the temporal and spatial distribution patterns of the deposits, based on the collection and organization of previous research results. The results show that the mineralization age of lead-zinc deposits is concentrated between 225 and 221 Ma, while the mineralization age of gold and silver deposits is concentrated between 238 and 197 Ma. Spatially, lead zinc ore, silver ore, and gold ore are successively produced outward from Shuangdinggou rock mass in Indosinian period as the center. The trace elements research indicates that the migration direction of ore-forming fluids is centered around Diannan - Zhenzigou area, moving towards the east and west sides and along the fault. Based on the study of the mineralization laws in the ore concentration area, and combined with recent field geological surveys, the authors established a preliminary geological model for prospecting prediction in Qingchengzi ore concentration area, wich could provide new ideas for promoting further prospecting work in the area.
