| 摘 要： | 本在系统分析下庄铀矿田火山岩的分布，火山岩系的旋回性，火山岩的岩石地球化学特征及火山岩的成岩时代等特征的基础上，较为详细地对下庄铀矿田的火山岩和赣南－粤北地区晚中生代武夷群火山岩各种特征进行了对比，厘定了下庄铀矿田火山夺为赣地－粤北地区晚中生代中火山岩系武夷群的组成部分；认为南岭铀成矿带今后寻找富矿，大矿的主要目标应该放在火山侵本和后火山侵入体的内外接触带上，以早期铀矿化（140－100Ma）为的主要目标类型。

| Abstract: | On the basis of systematic analysis of volcanic rock distribution,cycles of volcanic series,petrochemical characteristics of volcanic rocks,as well as geochronologic features of volcanic rocks,authors make a comparison of volcanic rocks in Xiazhuang uranium ore field with those of Late Mesozoic age (Wuyi Group)in southern Jiangxi northern Guandong in various aspects,and have discriminated that volcanic rocks in Xiazhuang uranium ore field are the constituents of Late Mesozoic Wuyi volcanic series.Then authors suggest that major efforts for locating rich large uranium deposits in Nanling uranium metallogenic belt must be aimed at the endo and exo contact zones of volcanic intrusive bodies and post volcanic intrusive massifs,and major target prospecting type should be the early uranium mineralization with the ore formation ages of 140-100 Ma. |
