摘　　要：盛源盆地位处赣杭铀成矿带中段,是华东地区重要铀矿田之一。在收集和分析大量放射性水化学特征数据基础上,运用统计分析及信息复合技术,详细研究了盆地放射性水化异常与已知铀矿化的关系,总结了放射性水化学找矿规律。认为铀-氦高值晕是成矿标志,铀-氡高值晕是近矿标志,单铀型水异常晕较好反映铀矿化的局部富集,氦水异常反映隐伏构造存在,可指示攻深找盲。据此,圈定Ⅰ、Ⅱ级成矿远景区各1处,Ⅲ级远景区3处,为盆地今后铀矿找矿提供了依据。Some data of radioactive chemical characteristics are collected and analyzed,on the basis of these data,the relationship between radioactive hydration abnormity of basin and known uranium mineralization are studied in detail,and the hydrogeochemical prospecting rules are summarized.The results show that high U-He halos value is a metallogenic indicator,high U-Rn halos value is an indicator of near ore,and single-uranium fluid abnormal halos can preferably reflect local enrichment of uranium mineralization,helium fluid abnormal halos can reflect the existing of buried structures and then indicate further exploring for deep deposit.According to the study result,one grade Ⅰ metallogenic prospect,one grade Ⅱ metallogenic prospect and three grade Ⅲ metallogenic prospects are delineated.The study can provide basis for further uranium prospecting in basin.
