摘要
The Qianjiaping vanadium deposit was hosted in the lower Cambrian black rock series. Analyses of the material phase, X-ray diffraction and electron microprobe observation suggest that the vanadium of the deposit is dominated by low valence, accounting for 74.22%, next is pentavalent vanadium, accounting for 25.78%. The vanadium occurrence is mainly same-phase in the micaceous minerals, accounting for 61.72%, secondly absorbed in the carbon base and clay minerals, and a little in the oxides. The mineral with vanadium mainly is roscoelite. The roscoelite has two types: 1M and 2M1. The vanadium is between the structural layers of the mica in the 1M type. Vanadium replaces aluminum not only in the six-ligand octahedral layer, but also in the Si-O tetrahedral layer.
