湖北兴山白果园黑色页岩型银钒矿床中银钒赋存状态研究

湖北兴山白果园黑色页岩型银钒矿床以其独特的赋矿岩性受到国内外地质学家的重视，其Ａｇ，Ｖ的赋存状态也受到人们的关注。在前人工作的基础上，采用中子活化分析，电子探针分析和质子激发Ｘ射线发射分析等方法对黑色页岩中Ａｇ，Ｖ的赋存状态进行了分析。结果表明，Ａｇ的无机态和有机态各占一定的份额，其中无机态７６．６３％，有机态２３．２７％；无机态中以独立矿物态和类质同象态为主，独立矿物态占总量的２８．８５％，类质

Occurrence of Ag and V of Baibuoyuan black shale hosted silver and vanadium deposit in Hubei Province, China

Due to its special hosted rock, Baiguoyuan black shale hosted silver and vanadium deposit in Hubei Province, China had shared great concern since it was discovered, and this was especially true of the occurrence of Ag and V. Based on the work documented, INAA, EPMA and PIXE were carried out to further determine the occurrence of Ag and V in this paper. It was clear that Ag occur both inorganically and organically, and Ag occurring inorganically accounts for 76.63%and Ag organically takes the rest. Among the inorganically occurring Ag, silver minerals and isomorphism predominated, and the former took up 28.85%while the latter 46.73%. However, V occurred predominantly inorganically, accounting for 97.41%; only 2.49%of V occurred organically. Inorganically occurring V was hosted mainly in illite and barite.
