摘要:
通过野外地质调查和室内岩石学、岩石化学、稀土及微量元素地球化学分析,深入研究了陕西省商南县湘河地区钒矿床的成矿特征,并探讨了该类矿床的成因。研究结果表明,该区钒矿主要产出于青石峡—余家台倒转复式向斜两翼下寒武统水沟口组下岩段硅质岩夹泥岩的泥岩中,矿体产状与地层产状基本一致;钒矿床中所有岩石都含有较高的SiO2,硅质岩以隐晶质石英和玉髓为主,有沉积成因重晶石;V与Cr、U、Ba相关性好;稀土元素球粒陨石标准化模式具有或正或负的Ce异常和明显的Eu正异常、向右倾的图形。上述特征都反映出该地区钒矿床具有典型的海底热水流体特征,此类钒矿床可称之为海底热水(喷流)沉积矿床。
Abstract:
Based on geological survey and analysis of petrology, lithogeochemistry, geochemistry of REE and microelement,the authors study metallogenic characteristics of V ore deposit in the Xianghe area of Shangnan County, Shaanxi, and discuss its genesis.Several conclusions are drawn from the study. The ore deposit mainly occurs in the lower Cambrian Shuigoukou Formation, which is situated at the limbs of Qingshixia-Yujiatai overturned multiple syncline. The ore-hosted rocks are silicalite and mudstone. The content of SiO2 is high in the rocks of V ore deposit. Silicalites are mainly aphanitic quartz and chalcedony and the barite is sedimentogenic. The correlation between V and Cr, U, Ba is good. The rare earth element distribution patterns show Ce-negative or positive anomaly, obviously Eu positive anomaly and the right dip graphics. These all suggest that V ore deposit has the characteristics of submarine hydrothermal spring.
