摘要
丹凤铀矿田位于北秦岭造山带东段的丹凤三角区内,是我国重要的花岗伟晶岩型铀矿床集中区。通过收集前人对丹凤铀矿田的相关研究资料,主要对区内花岗岩的岩相学、岩石地球化学、年代学等特征进行了总结。迄今为止,丹凤铀矿田研究程度尚浅,如矿物学、放射性蚀变特征、成矿时代、成矿流体等方面仍有待进一步研究。
Danfeng uranium ore field is located in the Danfeng triangle area of the eastern part of the North Qinling Mountains orogenic belt.It is an important granite pegmatite type uranium deposit concentration area in China.By collecting the previous research data on the Danfeng uranium ore field,this paper mainly summarizes the petrography,rock geochemistry and chronology of the granites in the region.So far,the degree of research in Danfeng uranium ore field is still shallow,such asmineralogy,characteristics of radioactive alteration,metallogenic age,ore-forming fluid and other aspects still need further study.
