南秦岭柞水—山阳矿集区成矿特征及找矿方向

Analysis on metallogenic characteristics and prospecting direction of Zhashui-Shanyang ore cluster in South Qinling Mountains

柞水—山阳矿集区是秦岭造山带重要的矿集区之一,近年来随着找矿勘查及研究工作的不断深入,铜、金等多金属矿床的找矿工作不断取得新突破,相继勘查发现多个大—中型矿床。越来越多的证据显示这些矿床的形成与晚侏罗—早白垩世构造-岩浆活动关系密切,矿床多就位于区域性三级控矿断裂及中酸性小岩体附近,矿区热液蚀变强烈,显示岩体活动提供了成矿作用所需的能量和物质来源。文章通过对柞水—山阳矿集区的地质、地球物理、地球化学、遥感等特征分析,划分了柞水—山阳矿集区的成矿构造带及成矿区带,提出下一步找矿方向,对矿集区找矿勘查工作具有重要的借鉴意义。

The Zhashui-Shanyang ore cluster is one of the important ore clusters in the Qinling orogenic belt.In recent years,with the continuous deepening of ore prospecting and research,new breakthroughs have been made in the prospecting of copper,gold and other polymetallic deposits.Successive surveys have found multiple large-medium deposits.More and more evidence shows that the formation of these deposits is closely related to the Late Jurassic-Early Cretaceous tectonic-magmatic activities.Most of the deposits are located near the regional third-level ore-controlling faults and small-acid rock bodies.Strong,showing that rock mass activity provides the energy and material sources required for mineralization.Based on the analysis of the geological,geophysical,geochemical,and remote sensing characteristics of the Laishui-Shanyang ore cluster,this paper divides the metallogenic structural belts and ore-formation zones of the Laishui-Shanyang ore cluster,and proposes the direction of ore prospecting,It has important reference significance for ore prospecting in the mining area.
