新城地区下寒武统黑色岩系分布广泛,蕴含着丰富的矿产资源,其中钒矿资源尤为丰富.钒矿体赋存于下寒武统牛蹄塘组的黑色炭质黏土岩中,钒矿(V2O5)的平均品位为0.64%,矿石主要类型为砂屑钒矿石.通过对成岩、成矿的研究,初步认为新城钒矿为海相化学及生物化学沉积生成,但可能也存在有淋滤成因.钒矿化受地层、岩性、岩相控制.%The Lower Cambrian black rock series are broadly distributed in Xincheng area, Guizhou Province, with rich mineral resources, especially vanadium. The vanadium deposits occur in the black carbonaceous clayrock of Lower Cambrian Niutitang formation. The average grade of V2O5 is 0.64%. The vanadium ore is mainly psammatic type. Study on the diagenesis and metallogenesis shows that the Xincheng vanadium deposit is genetically formed by marine chemical or biochemical sedimentation, with also eluviation origin. The mineralization is strictly controlled by strata, lithology and rock facies.
