摘要
"交点"型铀矿是下庄矿田今后找矿的主要矿床类型之一。铀矿化产于基性岩脉与区域断裂构造交汇部位,矿化及矿体产状由两者共同控制。在归纳分析区域断裂构造和基性岩脉与铀成矿作用关系的基础上,结合围岩蚀变、地幔流体及成矿物质来源,提出下庄矿田"交点"型铀矿的找矿方向及找矿标志,为该地区"交点"型铀矿的研究与勘查工作提供依据。
The intersection type uranium deposit is one of the main ore deposits which rank in priority in the future prospecting works in Xiazhuang ore field.Uranium mineralization occurs at the intersection of basic dike and regional faulted structure,which both control the mineralization and occurrence of the ore-bodies. Through analyzing the relation of regional fracture structure and basic dike with uranium mineralization,and based on the consideration of wall rock alteration,mantle fluid and ore-forming material source,this paper proposes the prospecting direction and clues for prospecting in intersection type uranium deposits within Xi-azhuang ore field,and it provides the important basis for research and exploration of intersection type urani-um deposits within the area.
