| 摘 要： | 硫是铁矿中的有害元素。峨口铁矿中硫主要以磁黄铁矿和黄铁矿两种形式存在。本区硫化物有三个形成期次。第五期为变质作用形成的星点状硫化物；第二期为变质后热液阶段形成的脉状硫化物；第三期为后期热液阶段形成的裂隙充填式硫化物。

| Abstract: | Sulfur is an unfavourable element in iron ore. Pyrite, pyrrhotin andchalcopyrite are the sulfur minerals in Ekou iron ore. Three formation stages have beenrecognized for these minerals.The first is metamorphic stage resulting in dotted .sulfurminerals.The second is fluid stage of late metamorphism resulting in laminated sulfurminerals.The third is hydrothermal stage after metamorphism resulting in crack - fillingsulfur minerals. Isotopic study shows that all the sulfides formed in the three stages havethe same sulfur provenance which is basic-ultrabasic volcanic rocks. The restoration fororiginal pre - metamorphic rock suggest that they be tholeiite of deep marine. The sulfurin the .sulfides born in iron ore and connecting rocks comes from their own sections of theore deposits. |
