Abstract: Qiancun Iron Deposit is a representative deposit in Yongzhen ore field，southwest of Ningwu ore district.The deposit is located at the southwestern side of Ningwu basin in the northern margin of Yangtze plate.The mining area belongs to Tanggou-Yuxikou anticline，two groups of faults are developed in NNE-NNE and NWW directions，the magmatic intrusion and mineralizaation in the mining area are controlled by NE trending fold structure.The magmnetic anomalies are developed obviously in the mining area，the deposit is a single magnetite deposit.8 magnetite orebodies are delineated in the mining area，the orebodies are distributed in the contact zone between diorite porphyrite and Huangmaqing Formation.Based on the latest geological prospecting results of the mining area，the geological characteristics and geophysical characteristics of the mining area，geological characteristics of the deposit are discussed，besides that，the deposit genesis is also analyzed.The study results show that:①the ore minerals are mainly for magnetite，followed by hematite and mumagnetite，and a small amount of chalcopyrite and bornite，ore types can be divided into massive，disseminated，veined and brecciated，genesis of Qiancun deposit is medium-high temperature magmatic hydrothermal contact metasomatism deposit；②according to the discrimination diagram of magnetite，the magnetite samples has fallen heavily into the porphyry deposit area，which further indicated that the prospecting potential of Cu-Au deposit in the mining area is good，the emplacement and metallogenic age of metallogenic rock mass are Early Cretaceous.
