摘要
棕树坑钨锡矿床地处南岭东西向构造岩浆带,是西华山—扬眉寺北东向成矿带的组成部分。含钨锡石英脉产于燕山中期隐伏花岗岩的外接触带。石英脉近东西走向,向南陡倾,尖灭再现、尖灭侧现和突然尖灭现象频繁。矿脉短小密集,呈东部收敛西部撒开展布,上小下大呈扇形下插于隐伏花岗岩隆起顶部。黑钨矿矿体中间富、上下贫,最富矿体在518~568 m中段上下。据矿化规律和工程控制程度,分析认为棕树坑边深部出水坑及螺形区段具有较大的找矿潜力。
Located in the east-west tectonic magmatic zone of Nanling, Zongshukeng tungsten-tin deposit is part ofthe Xihua Mountain-Yangmei Temple metallogenic belt. The quartz vein containing tungsten and tin was producedin the external contact of the Yanshan medium - term concealed granite, namely, the sand and slate of the Cambrianmetamorphic. The quartz veins are in the east-west direction with steep southward tendency. The short and denseveins are of the convergence in the eastern part and spread out in the west. The largest sized orebody is in the middleof 518？568 m. According to the law of mineralization and the degree of engineering control, it is concluded that thedeep effluent pits and spiral sections of palm trees have great potential for prospecting.
