陕西东秦岭多层金属矿成矿地质条件分析及深部盲矿预测研究

Metallogenic Geological Condition Analysis and Deep Blind Ore Prediction of East Qinling Multi-layer Metal Deposit in Shanxi Province

小秦岭金矿田断裂构造影响金矿的产出,且在断裂带中产状分布也会影响矿体的形态、产状和富集程度。研究表明,断裂的走向具有随机性,矿化具有强、弱相分布的特征。研究5505矿脉1号中段500 m以上断层构造控制条件及金矿控制规律,结果表明该矿脉受构造严格控制,深部第二矿化富集段低于1000 m。

The fault structure of Xiaoqinling gold field affects the gold production,and the middle distribution in fault zone will also affect the shape in occurrence and enrichment degree of ore bodies.The study shows that the strike of faults is random,and mineralization is characterized by strong and weak facies distribution.The results show that the ore vein is strictly controlled by the structure.The second mineralization enrichment section in the deep part is less than 1000 m.
