| 摘 要： | 水城黄塘发现的钒锌铅矿是迄今为止国内外已知的最富砷的钒锌铅矿，其中As2O3含量高达5．81％，属于钒锌铅矿与砷名矿的类同质同象系列。本文研究了它的产状、化学组成、X－射线衍射特征、红外光谱和稀土元素组成特征并与国外相似矿物进行了对比。结果表明，As在矿物中替代V进行矿物晶格，是原来的铅锌硫化物在表生条件经次生氧化形成，但V和As的富集机制还有待于进一步研究。 |

| Abstract: | Descloizite found in Hengtang of Guizhou Province is characterized by independent occurrence. The mineral is most enriched in arsenic all over the world with the highest As 2O 3 content of 5.81% , belonging to the isomorphous series between descloizite and arsendescloizite. The authors studied the occurrence, chemical composition, XRD characters, IR spectra and REE composition of the mineral and made comparisons with those from other locations in the world. It is concluded that arsenic in the mineral substituted vanadium and found its way into crystal lattice. The descloizite was formed by oxidization of lead and zinc sulfides under supergene conditions. However, further research is necessary for the mechanism of arsenic and vanadium enrichment. |
