一、概论产于前震旦纪五台系(鞍山系)古老变质岩系中的条带状铁矿(鞍山式铁矿),广泛的分布于全国各地,特别是在党提出全党全民办地质事业后,广大群众上山找矿,因此许多省都陆续发现了这类型矿床.根据最近了解,在湖南、山西、四川、甘肃、安徽等十几个省都找到这类型铁矿.这种类型铁矿一般来讲规模较大,产状简单,所以对保证钢铁工业大跃进具有现实的意义.在辽宁省条带状铁矿主要分布于辽南台背斜的中部及铁岭背斜的西北部,这一带均有规模不同的矿体出露.我国重要的纲铁联合企业—鞍山钢铁公司以及
I. INTRODUCTION The banded iron ore (Anshan-type iron ore) produced in the ancient metamorphic series of the Wunai (Precipitation in the Anshan) system of the Pre-Sinian is widely distributed throughout the country. In particular, After the cause, the vast masses of people looking for ore, so many provinces have discovered this type of deposit, according to recent knowledge, in Hunan, Shanxi, Sichuan, Gansu, Anhui, a dozen provinces have found this type of iron ore .This type of iron In general, the mine is large in size and simple in shape, so it is of practical significance to guarantee the Great Leap Forward in the steel industry. In Liaoning Province, the banded iron ore is mainly distributed in the central part of the Liaonan anticline and the northwest of the Tieling anticline All have different sizes of ore bodies exposed in China’s important iron rail joint enterprises - Anshan Iron and Steel Company and
