  <dc:description>&lt;p&gt;Thorium-free brannerite has been identified in Upper Devonian uraniferous sandstone from Penn Haven Junction, Carbon County, Pa. The brannerite was located by a variation of the "Lexan" technique and is associated with galena, uraninite, and clausthalite. The angular thorium-free nature of the brannerite suggests that it formed by metamorphism of uranium-saturated leucoxene. As a result of the metamorphism some uranium may be in less soluble minerals than those found in the uranium deposits of the Western United States. For this reason, in-place leaching of the uranium may be impractical.&lt;/p&gt;</dc:description>
