| 摘 要： | 南秦岭下寒武统黑色岩系形成于扬子地块北部被动陆缘裂谷裂陷盆地中,以发育巨厚的硅质岩、碳硅质岩、泥质岩夹碳酸盐岩、重晶石矿层为特征.沿控盆同生断裂运移的含钒的含矿热液被泥质岩吸附,构成矿源层,印支-燕山期自北向南顺层滑脱逆冲推覆,基底与盖层之间滑脱逆冲推覆韧性剪切带使得矿源层成矿元素活化迁移聚集成矿.牛山、凤凰山、平利基底隆起周缘是寻找钒矿的最有利区段. |

| Abstract: | The black rock series of Lower Cambrian in south Qinling are found in passive continental margin rift and depression basin of north Yangtze block,charactered by thick silicalite,carbonate-containing silicalite,claystone mingled with carbonatite and barite sheet.Vanadic mineral-bearing hydrothermal fluid migrating with control-basin growth fault is absorbed by claystone and provenance layers are formed.Owing to the consequent slipping thrust nappe from north to south in Indosinian to Yanshannian,ductile shea... |
