煤系地层中铁质矿物微观特征研究

Microscopic Feature Studies on Ferruginous Minerals in Coal Measures

摘要押通过对煤系地层中菱铁质鲕粒内部结构构造和黄铁矿、白铁矿微晶特征的研究,探讨了其生成的地球化学条件、形成机理,为地层对比、沉积地球化学条件的恢复等提供了依据。并对煤炭资源的勘探开发和利用具有实用意义。

Through studies on inner textures and structures of sideritic ooides and microlithic features of pyrite and marcasite, the paper discussed their genetic geochemical conditions and forming mechanics. Thus provided bases for stratigraphic correlation and remolding of sedimentary geochemical conditions, so the studies have application significance for exploration and exploitation of coal resources.
