| 摘 要： | 西澳大利亚州铁矿资源主要分布在北部皮尔巴拉和南部的伊尔岗两个太古宙克拉通。皮尔巴拉克拉通BIF型铁矿在汤姆普赖斯山、恰那和布鲁克曼的矿石矿物组合为假象赤铁矿一微板状赤铁矿，马拉曼巴的为赤铁矿一针铁矿，CID型铁矿在罗布河和杨迪矿石类型主要为褐铁矿；伊尔岗克拉通BIF型铁矿在库里阿诺的矿石矿物组合为针铁矿一假象赤铁，比温和曼迪尕的为磁铁矿±假象赤铁矿和针铁矿±赤铁矿。BIF型铁矿为浅生一变质成矿，而CID型铁矿则是先前形成的BIF经侵蚀、搬运、沉积和埋藏作用形成。

| Abstract: | Iron ore resources in the Western Australia State are mainly distributed in two Archean craton： Pilbara in the north and Yil- garn in the south. The Pilbara craton BIF type iron ore deposit mineral assemblage in Tom Price, Channar and Brockman is martite-mi- croplaty hematite, while in Marra Mamba is hematite-goethite; CID type iron ore deposit in Robe River and Yandi is mainly limonite. In Yilgarn craton, BIF type ore deposit mineral assemblage in Koolyanobbing is goethite-martite, while in Beebyn and Madoonga is magnetite _＋ martite and goethite ＋ hematite. The ore forming process of BIF type iron ore deposit is hypergene and metamorphism, while the CID type iron ore deposit is formed on preceding BIF type basis after erosion, transportation, deposition and burying. |
