相山河元背铀矿床近外围物化探异常特征及找矿效果

Geophysical and Geochemical Abnormal Characteristics and Ore-prospecting Effect in the Near Perimeter Area of Heyuanbei Uranium Deposit, Xiangshan Ore-Field

介绍了地面伽玛能谱和土壤天然热释光测量组合在河元背铀矿床近外围地区普查找矿中的应用效果;在对异常解释、推断的基础上,结合区内铀成矿地质背景及地面伽玛能谱和土壤天然热释光测量异常与已知矿床间的对应关系,圈出了4个找矿靶区;对其中的3号和4号靶区所在区域开展了进一步的铀矿普查工作,通过勘探在深部发现了受南北向苦命山-小陂断裂带控制的铀矿带,表明这两种方法组合可以较好地提供深部铀矿化信息,是该地区寻找隐伏铀矿体的一种有效的勘查方法组合。

The prospecting combination of ground gamma spectrometry survey and the soil natural thermoluminescence survey in the near perimeter area of Heyuanbei uranium deposit are described. Based on the anomaly interpretation, inference, combined with uranium ore-forming geological background in the region and ground soil natural thermoluminescence of gamma energy spectrum and measure the relationship between known deposits and abnormal, circled the 4 exploration target area; the 3rd and 4th Target region further uranium censuses were carried out, discovered through exploration in the deep North-South-Studio Pei to poor mountain fault zone control uranium mineralization demonstrated： the combination of both of these methods can provide better information of deep uranium deposits, is the for hidden in an effective exploration of uranium ore body combinations.
