摘要
界牌岭矿区位于湘南粤北海西—印支凹陷与赣湘后加里东隆起的接触带,圳口—瑶岗仙大断裂的西侧,南岭成矿带中段瑶岗仙钨锡铅锌多金属矿田的西南部,成矿地质条件优越,区内矿床由浅部特大型矿石矿床和深部锡多金属矿床两部分组成。本文通过区内成矿地质条件、矿体特征、成矿机理等方面的综合研究,推断矿区深部可能有更晚期的岩体,在晚期的岩体顶部可能存在以矽卡岩型钨锡多金属矿床为主的第二矿化富集区,并初步分析了深部找矿潜力,提出了具有找矿前景的区域,指明了找矿方向。
The Jiepailing mining area is located in the contact zone between the Hercynian Indosinian Sag in southern Hunan and northern Guangdong and the post Caledonian uplift in Jiangxi and Hunan,the west side of the Zhenkou Yaogangxian fault,and the southwest of the Yaogangxian tungsten tin lead zinc polymetallic ore field in the middle section of the Nanling metallogenic belt.The metallogenic geological conditions are superior.A super large ore deposit and a larger tin polymetallic deposit have been evaluated in the shallow part.Based on the comprehensive study of the metallogenic geological conditions,ore body characteristics,metallogenic mechanism,etc.in the area,it is inferred that there may be a more late rock mass in the deep part of the mining area,and there may be a second mineralization enrichment area dominated by skarn type tungsten tin polymetallic deposits at the top of the late rock mass,and the preliminary analysis of the deep prospecting potential is made,the areas with prospecting prospects are proposed,and the prospecting direction is pointed out.
