在加拿大地质调查所出版的经济地质从书第1卷“加拿大的铁矿床”(1965)一书里,作者把含铁沉积岩划分为富铁岩(ironstone,又译铁石和含铁建造(ironformation).在编写该书的过程中,认识到硅质含铁建造以两种主要类型产出,可以根据伴生的岩类、岩相特征及沉积环境进行分类(图1).这种分类发表后,对含铁建造及其伴生岩石的岩相地层、沉积作用、构造环境和背景又作了更详细的研究,结果证明,在含铁建造
In the Economical Geology published by the Canadian Geological Survey, in the book Iron Ore Deposits in Canada (1965), Volume 1, the authors classify iron-bearing sedimentary rocks as ironstone (ironstone, ironstone and ironformation) In the preparation of this book, it is recognized that the siliceous iron-bearing construction is produced in two main types that can be classified according to associated rock, lithofacies and sedimentary environment (Figure 1). After the classification was published , A more detailed study of lithofacies, sedimentation, tectonic setting and background of iron-bearing structures and their accompanying rocks has been conducted. The results show that in iron-bearing constructions
