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。

A quantitative appraisal of the prospect of uranium mineralization is completed based on a set of hydrochemical data acquired from the known in-situ leachable sandstone-type uranium, including radon content, acid-alkali ratio, oxidized and reduced electronic potential, hydrocarbonate radical and uranium content in water.

但是在找铀过程中仅用水化学成份、氡含量、酸碱度和氧化还原电位等数值进行描述，说明它们与铀矿化的关系，这种单一因素的描述不能综合反映与铀矿化的联系程度，以定量评价铀矿化与上述因素的关系，从而影响了水化学找矿的效果。

The Mo,U elements about normal geochemical method have a closely relationship with hidden uranium deposits. It has studied which methods is the most effective about this four methods through compare to drill material.After making compositive interpretation we can find this four method are effective on hidden uranium ore.We have the follow results: CR-39 track method and gama-ray spectrometer survey is better method than geochemical method.

最后通过这些单一方法实测测量结果与已知钻孔资料进行比较可以对该勘查方法的铀矿勘查效果进行评价；再从方法的单一研究到方法的综合研究，得出伽马能谱测量和固体径迹测量有效的结合，可以得到隐伏铀矿化的深部信息，而常规化探测量则可以有效划分近地表、深部铀矿化的区域。

It is difficult to study directly ore-forming hydrogeochemistry of sandstone type uranium ore in arid area, therefore, author have found out the laws of solution, precipitation and migration of uranium minerals in the groundwater using the mechanism of water rock interaction and uranium, thorium and their isotopic ratios, and have probed into the relation between uranium ore-forming hydrogeochemistry condition, hydrogeochemistry environment and uranium ore-body fixed position by studying the epigenetic hydrogeochemistry trackways in the rock.

由于干旱地区对砂岩型铀矿成矿水文地球化学研究困难，难以取水样直接研究。因而在研究方法上，作者运用水岩相互作用原理和铀钍及其同位素比值，查明地下水中铀矿物溶解、沉淀和迁移规律；通过研究岩石中留下的水文地球化学形迹，探讨铀成矿水文地球化学条件、水文地球化学环境及其与铀矿体定位的关系。

These problems are determining recharge area position, water source, uranium source of the groudwater in sandstone; the relation between partial discharge source of the groundwater in sandstone and uranium ore-forming; the relation between mineralizing hydrogeochemistry condition and fixed position uranium deposit or uranium ore-body or uranium mineralizing range; and relation between hydrogeochemistry trackways (such as, uranium, thorium concentrations; Th/U,〓U/〓U,〓Th/〓U, and 〓Th/〓U ratios etc) in the rock and uranium ore-body fixed position and so on.
