大水西钒矿体赋存于下寒武统中,矿床类型为黑色页岩型钒矿床,主要为石墨硅质板岩夹碳质板岩互层型钒矿石,局部矿段夹有硅质板岩、石英岩、石英片岩型钒矿石.钒矿物大多分布于云母类、高岭土矿物中,少数分布于电气石、石榴石类矿物中.矿石中钒呈分散状分布.用电子探针能谱对矿物物质组分进行微区元素组成分析,采用电子探针背散射电子成像分析技术和选区成分分析技术对内部结构矿物组成、元素赋存状态及特征进行研究.结果表明,钒除主要以V3+类质同象杂质替代铝硅酸盐中部分Al3+的形式及以独立矿物形式分散存在外,还有少量V4+以VO2+类质同象替代地开石(高岭石)中的Al3+存在,矿石中钒以钒独立矿物形式(可能为V-Ti或V-Ti-Si化合物、钒钛铁矿、V-Ti碳化物固溶体等)于矿石中产出.

The vanadium ore in Dashuixi occurrence in the lower Cambrian strata,it is black shale type vanadium de-posit,mainly of graphite siliceous slate clip carbonaceous slate interbedded type vanadium ore,the local ore section with siliceous slate,quartzite,schist type vanadium ore, vanadium ore in large part distributed in the mica,Kaolin mineral,the remaining distributed in tourmaline,garnet minerals,the distribution of vanadium are dispersed,using electron probe spec-troscopy on the mineral composition of micro elements of composition analysis,the backscattered electron imaging anal-ysis techniques and selection component analysis technology on the internal structure of the mineral composition,ele-ment occurrence and characteristics of vanadium,mainly in the V3+isomorphism substitute partial Al3+in aluminum sil-icate in the form of independent minerals present in the dispersion,a small amount of V4+in the presence of VO2+iso-morphous replace Al3+in dickite(kaolinite),vanadium output in vanadium deposit in independent mineral form (with V-Ti or V-Ti-Si compounds,sefstromite,V-Ti carbide solid solution,etc.).
