一富铁矿含铁建造形成条件“建造”一词在大地构造学术语中用得最多。一般用它来描述在大地构造发展过程中某一阶段形成的一大套复杂的层状岩石。现在流行的各学派根据其观点所划分的建造类型,一般都具有范围宽广、组成复杂的特点,对于成矿规律来说,掩盖着许多重要差别。在外国文献上经常使用的“含铁建造”(Iron—formation)一词,通常又仅指前寒武系沉积变质铁矿中条带状的贫矿层,连围岩也不包括在内,忽视了能说明铁矿沉积环境的许多重要标志。以上两种使用“建造”的涵义,一宽一窄,都是我们无法沿用的。在本文中我们将从与铁矿有密切成因联系的岩石共生组合特征来讨论我国富铁矿的
Iron ore rich iron ore formation conditions for the formation of “construction” in the terminology of tectonics used most. It is generally used to describe a large set of complex stratiform rocks formed at some stage during the development of the earth structure. The types of construction that the popular schools now make according to their point of views generally have a wide range of complex features that cover many important differences in the law of mineralization. The term iron-formation, often used in foreign literature, usually refers only to banded lean deposits in Precambrian sedimentary-altered iron ore, not even rock Many important symbols that illustrate the sedimentary environment of iron mines. The above two uses “construction” of the meaning of a wide and narrow, are we can not use. In this paper we will discuss the symbiotic characteristics of rocks associated with the close association of iron ores in China
