1980年,笔者在闽西南考察铁矿期间,在德化阳山铁矿区见到??状磁铁矿,这是冶金地质二队的同志在钻孔矿芯上首次发现的.含??粒的铁矿为致密块状,含铁50%左右.??粒直径1～2毫米,具同心圆环带构造,肉眼可见明显生长纹.??粒主要成分是磁铁矿,细粒至微粒结构;核心由泥质物、石英、透辉石、石榴石等组成.当矿石发育透辉石微细条带
In 1980, during the inspection of iron ore in southwestern Fujian, the author saw the magnetite magnetite in the Deyang Yangshan Iron Ore Mine, which was first discovered by the comrades of the Second Metallurgical and Geological Team on the drilling core. Granular iron ore is a dense block with iron content of about 50% .The grain diameter of 1 ~ 2 mm, with concentric annular structure, the visible growth of grain visible. The main component of the grain is magnetite, fine to Particle structure; core from the mud material, quartz, diopside, garnet, etc. When the ore development of diopside fine bands
