粤北瑶岭钨矿矿化类型多样性与叠加性研究

VARIETY AND SUPERPOSITION IN THE YAOLING TUNGSTEN DEPOSIT,NORTHERN GUANGDONG PROVINCE

粤北地处南岭钨锡成矿带的西南部,区内已发现众多规模大小不同的矿床(点),组成了著名的钨矿化集中区。瑶岭是其中一个中型石英脉型黑钨矿床,由于长期开采,瑶岭钨矿山原保有的黑钨矿资源储量濒临枯竭。2004年,在矿区南部碳酸盐岩与花岗岩岩体的接触带附近发现了夕卡岩型白钨矿化,不久又在矿区中深部的花岗岩体中发现了受断裂构造控制的构造蚀变型白钨矿工业矿化,揭示了钨矿化类型的多样性和叠加性。通过对区内不同类型钨矿化分布规律总结,将为钨矿化集中区新一轮的钨矿地质找矿工作提供新启示。

Yaoling mine in a middle scale wolframite deposit in the Nanling tungsten and tin mineralization area. Afar long time mining, wolframite reserve in the mine is near exhausted. In 2004, skarn type scheelite ores were found in the contacting zones between granite and carbonate rocks at south area of the mine. And then, structure -alteration rock type scheelite ores controlled by faults were found in the deep part of the granite of the mine. The newly found ores show variety and superposition of tungsten mineralization in the mine. Summary of different type tungsten mineralizing regularity can provide new inspiration, thinking, clue, target and type for tungsten prospecting in the northern Guangdong province.
