广东陆仔空铅锌多金属矿地质特征及成矿规律分析

Geological Characteristics and Metallogenic Regularity of Luzaikong Lead-zinc Polymetallic Mine in Guangdong Province

陆仔空矿区位于南岭成矿带中段,为大布铅锌铁多金属成矿带东。受新华夏系的构造影响,在区域旋转力下发育形成一个张扭性的帚状构造,后期为石英脉及富含有色金属的热液充填,根据环境与介质的不同产生了不同类型的矿体,分别为似层状矿体、矿化岩脉、石英(矽卡岩)—硫化物矿脉。为了对矿区外围地质找矿提供参考和依据,通过地质勘查资料对矿区铅锌多金属矿的地质特征、构造形迹进行分析并探讨成矿规律,最终确定矿区内矿体类型及矿体集中富集位置,并列举出除铅锌矿外其他有回收利用价值的金属矿物。

Luzaikong mining area is located in the middle of Nanling metallogenic belt and is the east of the Dabu lead-zinc-iron polymetallic metallogenic belt.Influenced by the structure of the Xinhuaxia system,a torsional braided structure develops under regional rotational force,and later is quartz vein and hydrothermal filling with non-ferrous metals.Different types of ore are produced according to the environment and medium.The bodies are layered ore bodies,mineralized veins,and quartz(skarn)-sulphide veins.In order to provide reference and basis for geological prospecting in the periphery of the mining area,the geological characteristics and tectonic traces of the lead-zinc polymetallic ore in the mining area are analyzed through geological exploration data,and the ore-forming rules are discussed,and the ore body type and ore body concentration and enrichment in the mining area are finally determined.Location,and list of other minerals that have recycling value in addition to lead-zinc mines.
