摘要
湖南双溪钒矿床产于寒武系下统木昌组,赋矿岩层为一套富含有机质的硅、磷、碳组合的黑色岩系.钒矿(V2O5)的品位为0.61%～1.51%,矿石主要分为3种类型:黑色碳硅质岩-页岩型、含磷结核页岩型及页岩型.钒的赋存状态主要有吸附态和类质同象态.通过对成岩、成矿的研究,初步认为双溪钒矿为海底喷气热水溶液同生沉积生成。
The Shuangxi vanadium deposit in Guzhang formation, which is composed of the black rock series County, Hunan Province occurs in Lower Cambrian Muchang rich in organic Si, P and C. The content of V2O5 in the ore ranges from 0.61% to 1.51%. The ore rocks can be divided into three types,i.e.black carbonaceous-siliceous rock-shale, phosphatic nodule-bearing shale and shale. The occurrences of vanadium are mainly in adsorption and isomorphism states. Study on diagenesis and metallogenesis shows that the Shuangxi vanadium deposit is formed by the syndepositon of submarine exhalative hydrothermal solution.
