摘　　要：通过对下庄矿田鲁溪地区笋洞岩体花岗岩特征,U含量、Th/U比值等特点进行研究,推测鲁溪地区具备较好的铀成矿物质来源。对铀成矿紧密相关的控矿构造和基性岩脉的展布特征、分布规模,揭露情况,以及与成矿紧密的绢云母化、绿泥石化、碳酸盐化等围岩蚀变进行了研究,预测鲁溪地区具有较大的铀成矿潜力。并根据成矿条件,把铀矿化类型确定为硅化带型和"交点"型。By studying the characteristics of the granite,uranium content,Th /U ratio of the Sundong rock mass in Luxi area of Xiazhuang ore field,the author infers that there is good source of uranium ore-forming materials in Luxi area. Based on the research of wall rock alterations which have a close relationship with mineralization,such as sericitization,chloritization,carbonatization and so on,we forecast that Luxi area has good potential for uranium metallization,and we confirm the uranium mineralization types as silicified zone-type and intersection-type according to the uranium ore-forming types.
