摘要
类比国内同类型矿床,对景德镇西北部八字脑锡(钨)矿矿床成因进行了初步探讨,认为燕山晚期第二次侵入的二云母—白云母花岗岩与成矿关系密切,北北东向断裂为区内主要的控岩控矿构造,在岩凸的顶部易形成蚀变花岗岩型矿体,而北北西向次一级张扭性裂隙控制着含锡钨石英脉带的分布和产状。成因类型属岩浆期后高温热液充填石英脉(带)型和蚀变花岗岩型锡钨矿床,从而来指导矿区深部及外围找矿工作。
The author discussed the Bazinao tin (tungsten) deposit in northwest Jingde Town of Jiangxi Province, in comparison with other similar deposits in China. The 2nd intruded bimica-muscovite granitic rock is considered to be closely related with ore-formation activities. The NNE fault is main ore-controlling structure and altered ore bodies formed at the top of the granitic body. The suborder NNW extensional fault decide the distribution of ore-bearing quartz veins. The ore types are post-magma thermal liquid filling quartz veins and altered granitic tin (tungsten) deposit. The author points out the dirction for deeper and surrounding exploration.
