摘要
文章分析了浙江铀区域成矿背景及分布特征,阐述了浙江火山岩型铀矿受区域构造、地幔隆起带、拉张裂陷作用控制,与不同级别、不同类型的火山构造有密切的关系。火山喷发带控制铀成矿带,火山喷发亚带控制铀成矿亚带,火山构造控制铀成矿区或铀聚源区,火山构造的特定部位及单体火山机构控制铀矿床的定位。通过研究认为芙蓉山盆地齐村—大城坞地段、天姆尖盆地下樟州地区、大洲盆地王贵寺南侧、新路盆地大桥坞地区是今后找矿的重点远景区。
U-ore deposits are of regional ore-forming and distribution background in Zhejiang province. The volcanics-hosted U-ore deposits are controlled by regional tectonics, mantle uplift and aulacogen and closely related to volcanic structure of different orders. Volcano-eruption belt controls U ore-forming area and U-concentration area; specific locality of the volcanic structure and the single volcano-apparatus, the location of U ore body. Researches and analysis of the above features show that Qicun-Dachengwu area in Furongshan basin, Xiazizhou area in Tianmujin basin, the south part of Yuguishi area in Dazhou basin, Daqiaowu area in Xinlu basin are the potential areas for futher U ore exploration in Zhejiang province.
