摘要
位于南秦岭的西成和凤太矿集区近年来找矿均取得了较大成果,其中西成矿集区在洛坝铅锌矿床东延发现郭家沟超大型隐伏铅锌矿床,凤太矿集区西端铅硐山-东塘子铅锌矿床在矿区深部发现规模较大的铅锌矿体。通过对比两个矿集区地质特征、矿体特征、控矿因素、富集规律以及成矿年龄,认为两者地质特征基本一致,铅锌矿走向一致,相向延伸,在深部可能相连,其接合部位具有一定的找矿潜力。借鉴西成和凤太矿集区成功找矿经验,建议在其深部利用广域电磁法及钻探等工作手段进行勘查。
In recent years,significant achievements have been made in mineral exploration in the Xicheng and Fengtai ore clusters located in the southern Qinling Mountains.Among them,the Guojiagou ultra large hidden lead-zinc deposit was discovered in the eastern extension of the Luoba lead-zinc deposit in the Xicheng ore cluster,and a large-scale lead-zinc ore body was found in the deep part of the Qiandongshan Dongtangzi lead-zinc deposit at the western end of the Fengtai ore cluster.By comparing the geological characteristics,ore body characteristics,ore controlling factors,enrichment patterns,and ore-forming ages of the two mining areas,it is believed that the geological characteristics of the two areas are basically consistent.The lead zinc deposits have the same direction,extend in opposite directions,and may be connected in the deep.The joint area has certain potential for mineral exploration.Drawing on the successful exploration experience of the Xicheng and Fengtai mining areas,it is recommended to use wide-area electromagnetic methods and drilling methods for exploration in their deep areas.
