摘要
矿区位于方山口-鹰嘴红山铁金铜镍钨钒铀磷成矿带,矿区内矿体赋存于下寒武统双鹰山组底部炭质板岩,受罗雅楚山复式向斜之次级构造控制。区内共圈定15条工业矿体,主要分布于罗雅楚山复式向斜之Ⅲ号背斜核部及南、北两翼,矿体长72m~1959m,延深12m~1296m,厚度1.04m~20.09m,平均厚度1.00m~4.78m,矿体平均品位0.541%~3.8276%。杨岭钒矿属喷流-沉积-变质型矿床。在成岩阶段,由于褶皱构造的发育,黑色岩系中的钒物质被炭质或粘土矿物所吸附而形成富矿层,炭质含量越高,含钒性越好,钒矿石品位越高。
The mining area is located in the Fangshankou-Yingzui Hongshan iron-gold-copper-nickel-tungstenvanadium uranium-phosphorus metallogenic belt.The ore bodies in the mine are deposited in the carbonaceous SLATE at the bottom of the Lower Cambrian Shuangyingshan Formation,which is controlled by the secondary structure of the Luoyachushan complex syncline.A total of 15 industrial ore bodies have been delineated in the area,mainly distributed in the anticlinal core of No.Iii and the south and north wings of the complex synclinal of Luoya,with a length of 72m~1959m,a depth of 12m~1296m,a thickness of 1.04m~20.09m,an average thickness of 1.00m~4.78m,and an average grade of 0.541%~3.8276%.Yangling vanadium deposit belongs to exhale-sedimentation-metamorphic type deposit.In the diagenetic stage,due to the development of fold structure,vanadium in black rock series is adsorbed by carbon or clay minerals to form a rich ore layer.The higher the carbon content,the better the vanadium bearing property and the higher the grade of vanadium ore.
