湖北大冶铁山铁(铜)矿床磁铁矿矿物化学及其成因的研究

A STUDY ON THE MINERAL CHEMISTRY OF MAGNETITE FROM TIESHAN IRON -COPPER MINERAL DEPOSIT, DAYE,HUBEI AND ITS ORIGIN

本文根据湖北大冶铁山矿床磁铁矿产出的地质条件及其矿物化学特征,从磁铁矿的化学组成及其相关关系、概率分布等方面着手,讨论了大冶铁山矿床的成因,认为该矿床主要为富镁的夕卡岩型矿床。为本矿床是夕卡岩成因的论点提供了矿物学的依据。

Tieshan ore deposit in Daye , Hubei is a large type of iron- copper ore deposit , as well known in China . For a long time , there have been several different views of genesis about the ore deposit . Based on geological circumstances and characteristics of mineral chemistry , the paper discusses the genesis of ore deposit in some aspects , such as chemical compositions and their relationships ,and the probability distribution of magnetite .It is believed that the Tieshan iron ore deposit primarily should be the Mg -rich skarn -type ore deposit .
