活性炭吸附氡法在尼日尔Teguidda地区砂岩型铀矿勘查中的应用

介绍了活性炭法测量原理、采取的质量保障措施以及在尼日尔Teguidda地区砂岩型铀矿勘查中的应用情况。通过在已知铀矿床的试验和工作区的应用表明,活性炭吸附氡法对地表和浅层矿化点以及深层铀源都有很好的反映,并能指示断裂信息。该法可作为确定有利找铀地段的重要依据,对指导本区深部找铀具有重要意义。

The Application of Radon Survey by Activated Carbon the Exploration of Sandstone-type Uranium Deposit in Teguidda, Niger

This paper described the application ofthe method of activated carbon survey in the exploration ofsandstonetype uranium deposits in Niger. The survey principle and the measures to ensure the survry quality were also introduced. Through the tests at known deposits, this method shew good response to ground mineralization, deep uranium sources and fault information. Good result had been obtained in the study area which indicated that this method can be used as an important evidence to determine the target area for uranium mineralization.
