关于前寒武纪条带状铁硅质沉积岩及其变质岩的国际命名,目前没有统一的意见.不同国家的文献中常见的术语有:铁燧岩(taconite)、铁英岩(itabirne)、碧玉铁质岩(jaspilite)、含铁石英岩(ferruginous quartzite)、含铁角页岩(iron hornfels)、含铁燧石(ferruginous chert)、含铁碧玉(ferruginous jasper)、铁矿石(ironore)等等.七○年召开的世界前寒武纪铁硅建造和锰建造的地质与成因讨论会上,有人提出了一个岩石命名的初步意见,现简介如下,仅供参考:“含铁石英岩”存在着三种认识:一是碎屑岩,二是变质作用片麻相的粗晶变质岩,三是包括所有铁硅岩石在内的随意运用的一个术语.
There is currently no uniform opinion on the international naming of Precambrian banded iron siliceous sedimentary rocks and their metamorphic rocks: taconite, itabirne, Jaspilite, ferruginous quartzite, iron hornfels, ferruginous chert, ferruginous jasper, iron ore and the like Etc. At the Symposium on the Geology and Origin of the Precambrian iron-silicon construction and manganese construction held in 1970, a preliminary opinion on rock naming was put forward. The brief introduction is as follows for reference only: “iron-bearing quartzite” There are three kinds of understanding: one is clastic rocks, the second is metamorphic gneiss coarse grained metamorphic rocks, the third is a term including the use of all iron and rock rocks, including a random.
