Title: Getting the Most Out of Previous HitRadonNext Hit Geochemistry: ABSTRACT

Author(s): Robert H. Morse

Article Type: Meeting abstract

Abstract:

Previous HitRadonNext Hit and radium are specific indicators of uranium. Previous HitRadonNext Hit in particular is easily analyzed in the field or in a portable lab. For this reason and because of its mobility as a soluble noble gas, Previous HitradonNext Hit has received considerable attention in exploration. The mobility of Previous HitradonNext Hit is complicated by its short half-life (3.8 days) and by movements of earlier members of the decay series.

Claims of the successful application of Previous HitradonNext Hit geochemistry to detect uranium deposits beneath several tens of meters of cover (including shale and coal beds) seem extravagant but may warrant further study. In areas of shallow overburden, Previous HitradonNext Hit in soil gas can extend evaluation to depths beyond reach of the scintillometer. Previous HitRadonNext Hit to thoron ratios are useful in this work as well as Previous HitradonNext Hit content itself. Day-to-day variations of Previous HitradonNext Hit content in soil gas are confusing, but seldom obscure trends and anomalies.

Lake-water Previous HitradonNext Hit anomalies are associated with two recent major uranium discoveries in the Canadian Shield. In both discoveries, the Previous HitradonNext Hit anomalies were detected in the earliest stages of exploration in the area.

Radium, the parent of Previous HitradonTop, also can be readily determined in a portable laboratory. In an example from southeast Texas, a dramatic reduction in radium values has been measured in groundwater within a few hundred feet of an orebody. Anomalous radium measurements other than those associated with uranium mineralization or geothermal waters are extremely rare.
