大冶铁矿矿石特征

Characteristics of Daye Iron Ore

通过对大冶铁矿矿石的光片与薄片的镜下观察,脉石矿物有:透辉石、绿帘石、石榴子石、石英、方解石,矿石矿物有:磁铁矿、方铅矿、黄铁矿、黄铜矿。岩石含有大理岩、矽卡岩、辉岩在内的一些岩浆岩。继而验证其接触交代作用的成因说,并使得读者更好更深刻的了解矽卡岩型铁矿床的矿物组成和矿物特征。

Through the observation under microscope of gloss coal and ore chip of iron mine mineral in Daye, we know that rocky mineral include diopside, epidote, garnet, quart, calcite, ore mineral include magnetite,galena,pyrite,chalcopyrite. rock include griotte,skarn, pyrozenite and some magmatites, such as pyrozenite.and then the thesis try to examine the cause of contact function and make readers have a better and deep understanding of mineral composition and characteristics of iron deposit of skarn.
