摘要
长城岭锑铅锌多金属矿位于南岭多金属成矿带中部,经历多期次构造—岩浆—成矿作用,成矿条件优越。通过资料收集及实地地质调查,综合分析矿床地质特征,总结成矿规律,明确找矿标志和找矿方向。研究表明:该矿床为中低温热液矿床,燕山期岩体为锑铅锌矿体提供了成矿物质来源。从成矿序列变化趋势分析,锑铅锌矿体深部有较大的找矿前景;锑铅锌矿体受断裂构造控制明显,多组构造叠加处是成矿有利空间;硅化是矿区成矿最有利的蚀变,特别是锑矿体与硅化体关系密切,围绕硅化体开展锑矿找矿潜力较大。
The Changchengling antimony-lead-zinc polymetallic deposit is located in the central part of the Nanling Polymetallic Metallogenic Belt,having undergone multiple phases of tectonic-magmatic-mineralization processes with superior metallogenic conditions.Through data collection and field geological surveys,this study comprehensively analyzes the geological characteristics of the deposit,summarizes metallogenic patterns,and proposes prospecting indicators and directions.Research indicates that this deposit belongs to a medium-low temperature hydrothermal deposit,with Yanshanian intrusions providing the mineral source for Sb-Pb-Zn orebodies.Analysis of metallogenic sequence evolution suggests significant prospecting potential at deeper levels of Sb-Pb-Zn orebodies.The ore bodies show clear structural control by faults,with structural superposition zones constituting favorable metallogenic spaces.Silicification represents the most favorable alteration type in the mining area,particularly showing close genetic relationship with antimony orebodies,indicating substantial antimony prospecting potential around silicified bodies.
