陕西丹凤地区密集分布着众多的花岗伟晶岩脉,由于其含有丰富的铀、稀有金属矿产及非金属矿产,一直以来备受地质工作者关注。前人的工作重点关注于花岗伟晶岩与矿产之间的关系,且有人认为含铀花岗伟晶岩与片麻状花岗闪长岩有成生关系,但对其构造意义的研究欠缺。作者通过参与《陕西1∶5万龙驹寨、峦庄街幅区调》项目,对花岗伟晶岩的年龄、成因及进行了研究,同时结合项目最新成果对其构造意义进
Many dense granite pegmatites are distributed in Danfeng area of Shaanxi Province. Due to their rich content of uranium, rare metal minerals and non-metallic minerals, geology workers have always been concerned by many geologists. The predecessors’ work has focused on the relationship between granitic pegmatites and minerals. Some people think that uraninite-bearing pegmatites are associated with gneissic granodiorites, but the study on their tectonic significance Lacking. The author studied the age, genesis and origin of the granitic pegmatite by participating in the project of “1: 50000 Longju Village and Luanzhuang Street Area in Shaanxi Province”, combined with the latest achievements of the project,
