摘    要:The iron deposit of Zaoanzhnang type occurs in the ultrabasie unit od a late Archaean greenstone belt. It is a late magmatic apatite-titanomagnetite deposit, subusequently enriched by hydrothermal superimposition and regional metamorphism. This deposit is extremely complex in mineralogy, containing 87 kinds of minerals charaeteristie of ultrabasie-alkaline complexes. Mineralization of iron, titanium and phosphorus took place mainly during the magmatic stage, while that of uranium and thorium during the pnenmatolytic-hydrothermal stage.
