摘要
略阳县陈家坝地区位于勉略阳三角区中部的徐家坝-陈家坝-七里沟多金属成矿带中段,区内断裂构造发育、中酸性火山岩广泛分布、变质作用强烈、异常套合好,已发现了多个与古火山作用有关的多金属矿床(点)。通过对区内成矿地质条件、物化探异常特征、矿化富集规律等综合分析,结合找矿实践开展了成矿预测及前景分析,优选出陈家坝矿区深部和秦家贬-红土石一带两个重点找矿地段。初步认为本区具有寻找大型铜锌多金属矿床的基本条件。
Lveyang county is located in the middle of Xujiaba-Chenjiaba-Qiligou polymetallic metallogenic belt in the central part of the Mianlueyang triangle.The fault structure is developed,the medium-acid volcanic rocks are widely distributed,and the metamorphism is strong.A number of polymetallic deposits(points)associated with ancient volcanism have been discovered.On the basis of previous studies,through the comprehensive analysis of ore-forming geological conditions,geophysical and geochemical anomaly characteristics,mineralization and enrichment laws,combined with prospecting practice,the ore-forming prediction and prospect analysis of the area are carried out.There are two key prospecting areas in the deep part of the dam mining area and the Qinjiatun-red earth stone area.It is preliminarily believed that this area has the basic conditions for finding large copper-zinc polymetallic deposits.
