Zhongbazi Ti magnetite deposit is late magmatic differentiation mineral deposit, which is infrequent in Mian-Lue-Ning triangle area in Lueyang County, Shaanxi Province. Its main ore-controlling factor is Mid-Late Proterozoic gabbro-diorite complex which intruded into the Bikou volcanic rocks group along the deep faults. The authors systematically collate the geological characteristics of the deposit, analyzing and summarizing the ore-controlling geological characteristics factors and indicate the next prospecting direction in this region, so as to service in the correlative exploration and research of iron deposit in the triangle areas.
