摘要文章论述了华东火山岩型铀矿找矿值得重视的地质问题:①铀成矿既可形成于浅源浅成低温条件,也可形成于深源深成高温或深源浅成中低温条件,在强调深源时,不是简单地认为是幔源就可以了,还必须强调壳幔作用的地质过程;②打破人为的&类型&划分,加强&铀成矿系统&的研究,更好地指导找矿;③研究基性脉体与铀成矿问题应注意构造、岩石矿物成分、成因、蚀变与成矿3大问题,注意寻找泥岩化作用强烈的破碎辉绿岩脉中的富铀矿;④火山盆地基底对铀成矿的作用主要是提供铀源,将基底对铀成矿的影响从感性认识推向理性认识,有效地指导找矿;⑤红盆与铀成矿关系可以从构造、古气候及时间分析研究中得出结论,它不仅仅是一个理论问题,而且有助于铀成矿预测;⑥隐爆角砾岩筒是铀成矿、成富矿的重要储矿构造,是华东火山岩型铀矿找矿的新领域。
