福建宁德九曲岭含铜钨矿隐爆角砾岩筒地质特征及其找矿意义

The Geological Characteristics and Its Meaning for Ore Prospecting of Cryptoexplosive Breccia Containing Copper-tungsten Ore in Jiuguling County of Ningde City,Fujian Province

宁德九曲岭含铜钨矿隐爆角砾岩筒出露于花岗闪长岩体之中,未见明显断裂控制,隐爆角砾成分与胶结物成分复杂,矿化蚀变具明显的分带特征,其中铜钨矿贮存于黄铁矿-绿泥石和石英—绿泥石带中。外围尚发现2个大型隐爆角砾岩筒,通过研究九曲岭铜钨矿角砾岩筒特征,对指导深部与外围找矿具有重要找矿意义。

The cryptoexplosive breccia containing copper-tungsten ore is outcropped in granodiorite pluton in Jiuquxi County of Ningde City, and isn＇t controlled by the obvious fault. The composition of cryptoexplosive breccia and agglutinate are complexity, mineralization alteration have obvious zoning characteristics. The copper-tungsten deposit exists mostly in the iron pyrite-chlorite and quartz-chlorite and Two large cryptoexplosive breccia have been discovered in the periphery. Based on the characteristics of cryptoexplosive breccia in Jiuquling copper-tungsten deposit, there is tremendously significant for ore-hunting in depth and periphery.
