摘　　要：南美地区蕴藏了丰富的铀矿资源。通过对砂岩型、石英卵石砾岩型、钙质结砾岩型、火山岩型、花岗岩型、交代岩型6种类型11个矿区进行研究,总结了它们的地质特征,初步划分出中安第斯、阿根廷北部、丘布特和南美东部4个铀矿成矿带,优选出几处铀矿资源潜力区,希望对"走出去"铀矿地质研究工作提供参考。South America possesses abundant uranium resources.The authors recognized six deposit types,i.e.,sandstone,paleoquartz-pebble conglomerate,calcrete,volcanic,granite-related and metasomatite types,and selected11uranium deposits of the6types to analyze and summarize their geological features.Based on the study,the authors preliminarily delineated four uranium metallogenic belts in the continent,i.e.,mid-Andean,Northern Argentina,Chubut,and Eastern South America metallogenic belts,and preferentially proposed several potential areas of uranium resources in the hope of providing some information for the‘going out’of uranium ore geologists.
