| 摘 要： | 中国的"鞍山式"(沉积变质型)铁矿常以"大、贫"著称,但鞍山-本溪地区许多铁矿床中赋存有富铁矿,其中弓长岭铁矿中的富铁矿资源量超过亿吨.通过对鞍本地区"鞍山式"铁矿的分布特征、典型矿床富铁矿体特征的研究,提出了本地区变质改造形成的富铁矿分布在一条东西长85 km、南北宽25 km范围内的认识,并认为中生代花岗岩可能也参与了部分矿区富铁矿的形成过程.

| Abstract: | The Anshan type sedimentary-metamorphic iron deposit in China is famous for "being large and poor". However, high-grade iron orebodies are hosted in many deposits in Anshan-Benxi region, among which the rich iron ore resources of Gongchangling deposit exceed one hundred million tons. With study on the distribution regularity and characteristics of typical high-grade iron orebodies, the authors recognize that the rich iron orebodies are formed by regional metamorphic reformation, distributed in the range of 85 km long from west to east and 25 km wide from north to south. The Mesozoic granites may also be involved in the formation of some rich iron orebodies. |
