摘要
古者钒矿产于下寒武统牛蹄塘组底部一套含硅、碳、泥质的黑色岩系中。矿体呈层状、似层状,产状稳定。矿石主要由伊利石和石英、炭泥质组成。矿层平均厚度为2.96m,V2O5平均品位为0.87%。钒矿化受地层、岩相、岩性、古构造和古地理条件控制。分析认为:区内钒矿的生成与菌藻类活动密切相关,属于化学-生物化学沉积成因的矿床。
The Guzhe vanadium deposit is hosted in the carbonaceous,siliceous and argillaceous balck rock strata of Noutitang Formation of the Lower Cambrian.Orebodies are presented in layer and layeroid shape with stable occurrence.The ore is mainly composed of illite and quartz,argillous and carbonaceous component.The average ore-layer thickness is 2.96m,and the average grade of V2O5 is 0.87%.The vanadium mineralization is controlled by the strata,lithofac,lithological feature,paleo-structure and paleo-geographic condition.According to the comprehensive analysis,the production of vanadium ore in the area is closely related to the activity of algae and bacteria,and the vanadium deposits belong to the chemical-biochemical sedimentary genesis type.
