Hypogene high thermal or deep source epi-mesothermal condition and it is not only stressed the mantle source simply but also the crust-mantle;②in order to guid ore exploration better the artificial classification of uranium deposits should be broken and uranium ore-forming system strengthened;③much attention should be paid to searching the diabase-hosted rich uranium ore in strongly argillized cataclastic zone;④attention should be paid to the influence of basement of volcanic basin on the uranium ore formation that should be undstood both in feeling and theoretically through the ore propect process;⑤relation of red basin with uranium ore formation can be made clear from analyzing tectonics, paleo-climate and time and it is not only theoretically important but also helpful to uranium ore prediction;⑥crypto explosive pipe is an uranium ore, rich uranium ore host structure and it is the next goal for uranium ore exploration in east China.

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。
