| 摘 要： | 通过对惠民式和疆峰式铁矿的研究,认为它们都是受变质中基性火山岩建造控制的海相火山-沉积型铁矿床,前者兼有条带状含铁建造(BIF)和粒状含铁建造(GIF)的特征,而后者则为条带状含铁建造.它们均具备元古代条带状铁硅建造铁矿的特征,满足形成前寒武纪大型条带状含铁建造的“大型海洋热液供应系统、作为沉积仓储的大陆架体貌及有能力...

| Abstract: | A study of the Huimin-and Jiangfeng-style iron deposits has revealed that the marine volcanogene sedimentary type Huimin and Jiangfeng ore deposits are controlled by metamorphosed intermediate-basic volcanic formation.The former(Huimin-style) consists of both banded iron formation(BIF) and granular iron formation(GIF) whereas the latter(Jiangfeng-style),consists only of banded iron formations(BIF).The possess of the formation of Proterozoic bended siliceous iron formation possesses the features of a large-s... |
