Abstract: Taking the Heigouxia phosphate deposit in Huangzhong County and the Shangzhuang phosphate deposit in Ping'an District, Qinghai Province as research objects, this paper analyzes the geological characteristics and metallogenic conditions of sedimentary metamorphic phosphate deposits and magmatic phosphate deposits, and discusses their metallogenic mechanism. Furthermore, this paper summarizes the metallogenic regularity of phosphate rock in the Qinghai Province, and predicts the prospecting direction of phosphate rock, which has certain guiding significance for the future prospecting and research of phosphate rock in Qinghai Province.
