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。

Using many geoscientific methods, the formation mechanism and u ranium mmeralization of the Mesozoic-Cenozoic fossil hydrothermal sys tems, Southeast China, have been discussed for the first time through comprehensive studies of the two typical Mesozoic-Cenozoic uranium ore forming fossil hydrothermal systems—Xiangshan Volcanic Rock Type U ranium Ore-field and Xiazhuang Granite Type Urani um Ore-field by integration of "Three sources: Uranium and its Mineralizer Source, Water Source and Heat Source".
