hematite

The iron oxides in rock crystals are specularite, hematite and lepidocrocite.

晶体中氧化物包裹体为镜、、纤。

The Ningxiang-type iron deposit in western Hubei is widely-spreading and of large-size and is characterized by hematite ooid.

鄂西宁乡式分广、规模大,普遍发育鲕粒。

The mineral assemplege of the deposit is composed of diaspore, kaolin, illite, chlorite, hematite, anatace and rutile with tourmaline, zircon, goyazite in less.

该的物组成为一水硬铝石、高岭石、伊利石、绿泥石,、锐钛和金红石。此外,还有电气石、锆英石、磷铝锶等微量物。

For sinter with 25% and 50% MAC fines the iron oxides mainly consisted of hematite and magnetite, the bonding phase were mainly dicalcium silicate, glassiness, and a few amount of calcium ferrite.
