陕西省略阳县陈家坝地区铜锌多金属矿床成矿地质条件及找矿前景分析

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。

Ore forming geological conditions and prospecting potential of Cu Zn polymetallic deposit in Lueyang, Shaanxi

The chenjiaba area of Lueyang county is located in the middle of polymetallic metallogenic belt in the middle seven Mian Lueyang Delta region Xujiaba - chenjiaba - ditch area faults, acidic volcano rocks are widely distributed, strong metamorphism, very close, has found a number of ancient volcano in polymetallic deposit the (point). On the basis of previous studies, based on the ore-forming geological conditions, geophysical and geochemical anomalies, mineralization enrichment regularity of the comprehensive analysis, combined with the prospecting practice carried out analysis and Prospect of mineralization in the region, select the chenjiaba in deep and Qin - red earth area down 2 key prospecting areas. It is considered that this area has the basic conditions for searching for large copper zinc polymetallic deposits.
