赤铁矿的产状与组合
Hematite ore occurrence and combination
形成于氧化条件下,规模巨大的赤铁矿矿床多与热液作用或沉积作用有关。赤铁矿可成沉积变质型铁矿,主要由磁铁矿、赤铁矿、假像赤铁矿所组成,与石英、绿泥石等共生。接触变质型的赤铁矿主要与磁铁矿、黄铜矿、斑铜矿、磁黄铁矿等硫化物和石榴子石、透辉石、金云母、阳起石等共生。在自然界,磁铁矿和赤铁矿可相互转化。当氧逸度增大时,磁铁矿可氧化成赤铁矿;若仍保留有原磁铁矿的晶形,称之为假象赤铁矿。若磁铁矿仅部分转变为赤铁矿,则称为假赤铁矿。而当氧逸度减小时,赤铁矿又可还原成磁铁矿;若仍保留有赤铁矿的晶形,则称之为穆赤铁矿。
Formed in the oxidation condition, the enormous scale of hematite ore deposits related with the hydrothermal activity or sedimentation. Hematite can be metamorphosed sedimentary iron ore, is mainly composed of magnetite, hematite, martite composed, symbiosis and quartz, chlorite. The contact metamorphic type hematite and magnetite, chalcopyrite, main coexisting bornite, magnetic pyrite and garnet, diopside, phlogopite, Yang Qishi etc.. In nature, magnetite and hematite can be transformed into each other. When the oxygen fugacity increases, magnetite can be oxidized to hematite; if still retains the original magnetite crystal, called false hematite. If only partially transformed into magnetite hematite, then known as the false hematite. When the oxygen fugacity decreases, hematite and magnetite can be reduced to; if still retains the Hematite crystal, it is called the mu hematite.
