粤北花岗岩型铀矿找矿潜力及找矿方向

深部构造环境、长期活动的深大断裂和成群成组的成矿构造带、多期次构造岩浆活动和蚀变叠加、多期次地幔流体和成矿流体的频繁活动，以及花岗岩丰富的铀源、良好的还原条件和封闭成矿环境等优越的成矿条件，使粤北成为得天独厚的花岗岩型铀矿矿集区。通过分析下庄矿田330南西地区“群脉型”、中洞地区“交点型”铀矿化，以及南雄矿田坪下水地区、棉花坑-书楼丘地区“硅化碎裂岩型”铀矿化等成矿条件好、找矿线索明显的地区，表明区内有较大的铀资源潜力和找矿潜力，为下一步的工作指出了方向。

Prospecting potential and direction for granite uranium deposit in north Guangdong, China

North Guangdong is an unique ore cluster of granite uranium deposit resulted from the super condition of the following factors:deep and large scale fault of long activity and grouped metallogenic structures,multiphase tectonic-magamatic activity and superimposed alteration,multi-phase activity of mantle and metallogenic fluid,abundant uranium source from granite,favorable reductant and closed metallogenic setting.This paper does study and analysis in favorable areas with outstanding prospecting clue for various type mineralization,they are uranium mineralization of "group vein type" in the southwestern district of deposit 330 in Xiazhuang ore field,mineralization of "intersection point type" in Zhongdong area,mineralization of "silicated cataclastic rock type" in Xiashuipin and Mianhuaken-Shulouqiu area of Nanxiong ore field.The research shows that there are fairly good resource and prospecting potential in North Guangdong and the effort direction is pointed out for further exploration.
