摘要
通过对邬郁盆地地质特征和后生改造条件的分析,盆地基底及蚀源区具有铀源层与铀源体,盖层中中酸性火山岩、火山碎屑岩分布广泛且存在含铀层,盆中断裂构造发育,具有多期活动与热液蚀变,盆地盖层主体宗当村组(N2z)中已发现了铀矿体和异常点(带),提出邬郁盆地具有寻找砂岩型铀矿和火山岩型铀矿的条件。
Study of geological characteristics and subsequent reformation indicates that there exists uranium source bed in the bottom of the Wuyu basin; intermediate-acid volcanic rock and pyroclastic rock are widely distributed over the basin; fault structures were developed in the basin; multiple hydrothermal activities and alteration took place. Uranium orebody and U anomalies has been found in the Zongdangcun Formation. There are potentiality of sandstone type and volcano type U-ores in the basin.
