甘肃省肃北县大水泉钒矿地质特征及找矿规律研究

Study on Geological Characteristics and Prospecting Rules of Dashuiquan Vanadium Deposit in Subei County,Gansu Province

大水泉钒矿床位于方山口―七角井子—白山堂金、铜、镍、钨、锰和钒-磷-铀成矿带西段,为沉积型矿床,矿体受层位控制明显,赋存于下寒武统双鹰山组碳质板岩、含碳硅质板岩组成的黑色岩系,赋矿岩性为碳质板岩,底板为白云岩,顶板为硅质板岩,属于碳质板岩型钒矿石,大水泉钒矿带累计长3.70 km,矿体长70~1 300 m,厚度1.02~26.34 m,平均品位V2O5 0.73%~1.51%,矿体总体呈近东西延伸,倾向总体北倾。大水泉主矿体V1-4地表品位高、厚度大,适合小规模开发利用。
