陕西省凤县二里河铅锌矿深部找矿预测
|
摘要
勘查区位于秦岭泥盆系贵金属-多金属成矿带凤太矿集区中部偏北,区内所发现的大、中型铅锌矿床均具有相同的"硅钙面+背斜构造"控制的成矿特征,铅锌矿体受"背斜+地层+岩相"三位一体控制,产于背斜构造的鞍部及翼部、中泥盆统古道岭组灰岩与上泥盆统星红铺组千枚岩接触带,含矿岩性主要为硅化灰岩。
The Erlihe lead-zinc deposite was located in the middle-northern part of the Fengtai orefield within the Devonian muti-metal metallogenic belt of Qinling.Both large and moderate lead-zinc deposites were controlled by the calcium silicon surface and anticline,meanwhile,the deposite was controlled by the comprehensive elements including anticline,strata and petrology.It was mainly developed in the saddle and limb,both were belonged to the contact zone between the Middle Devonian limestone in the Gudaoling group and Upper Devonian phyllite in the Xinghongpu group.Among them,the silicified limestone contained the mainly ore resources.
