摘要
放射性水文地球化学找矿以其快速、简便、经济和高效的优点在丹凤地区花岗伟晶岩型铀矿勘查的各个阶段发挥了重要作用,浅层地下水放射性异常晕与含矿黑云母花岗伟晶岩分布范围一致,可用于圈定铀成矿远景区、普查区和详查区。近矿中深层地下水具有高U-Rn放射性水文地球化学特征,通过工程放射性水文地球化学找矿,可预测盲矿体大致位置,指导揭露工程布置。
Hydrochemical radioactive prospecting plays an important role in the all stages of grano-pegmatite type uranium deposit exploration in Danfeng area dut to its fast,simple,economic and high effective advantage.Radioactive anomalous halo in the shallow underground water has identical distribution scopes with the ore-bearing biotite granite-pegmatite,which can be used to delineate uranium ore-forming prospective area,reconnaissance area and detailed prospecting area.Deep underground water close to the ore is characterized by hydrogeochemical radioactive features with high uranium and radon content.Through prospecting engineering of radioactive hydrogeochemical,the situation of blind ore bodies can be used to guide the layout.
