GEOLOGICAL CHARACTERISTICS AND ORE-CONTROLLING FACTORS OF WULANWUSU PHOSPHATE DEPOSIT IN WESTERN LIAONING PROVINCE
Wulanwusu phosphate deposit,one of the important phosphate deposits in western Liaoning Province,has a large-scale resource reserve and associates with beneficial component(magnetite).The phosphate orebodies are occurred in the Neoarchean Xiaotazigou complex,mainly controlled by greenstone-type phosphorus magnetite formation.The ore mineral assemblage includes apatite,magnetite,titanomagnetite,hornblende,biotite and plagioclase.The apatite content is positively correlated with the content of dark components such as iron,titanium and manganese,indicating the siderophile affinity of phosphorus.The deposit is of metamorphic apatite type genetically.
