麻阳县尧市钒矿地质特征及成因分析

Analysis on Geological Characteristics and Genesis of Yaoshi Vanadium Deposit in Mayang County

凭借独特的物理化学性质,钒金属广泛应用于钢铁、航空航天、化学、电池、颜料、玻璃、光学和医药等领域。作为钒资源大国,我国钒总资源量、产量和消费量均位居全球第一。麻阳苗族自治县(简称麻阳县)位于湖南省西部,由怀化市管辖,矿产资源丰富。结合区域地质背景,分析麻阳县尧市钒矿的矿床地质特征,明确矿床成因。研究区内,寒武系纽芬兰统牛蹄塘组(∈1n)的含磷结核炭质板岩为主要钒矿赋存层位。从矿床成因来看,麻阳县尧市钒矿属生物化学沉积矿床。

With its unique physical and chemical properties,vanadium metal is widely used in fields such as steel,aerospace,chemistry,batteries,pigments,glass,optics,and medicine.As a major vanadium resource country,China ranks first in the world in terms of total vanadium resources,production,and consumption.Mayang Miao Autonomous County(abbreviated as Mayang county)is located in the western part of Hunan province,under the jurisdiction of Huaihua city,with abundant mineral resources.Based on the regional geological background,the geological characteristics of Yaoshi vanadium deposit in Mayang county is analyzed,and the genesis of the deposit is clarified.In the study area,the phosphorus bearing nodular carbonaceous shale of the Cambrian Terreneuvian Niutitang Formation is the main occurrence layer of vanadium deposits.From the perspective of ore genesis,Yaoshi vanadium deposit in Mayang county belongs to a biochemical sedimentary deposit.
