Nature and Role of Organic Matter in Sandstone Uranium Deposits, Grants Uranium Region, New Mexico, Nuclear magnetic resonance analyses, elemental abundances, and isotopic studies provide further constraints on the nature of the organic material, and data from these studies are consistent with a humic acid rather than an oil origin. In addition, the overall tabular shape of primary uranium orebodi

Die einzelnen Geisteskrankheiten,es. By weathering at out-crops etc., all migrabitumens become more or less oxidized. Such oxidized bitumens can have characteristics similar to diverse unaffected migrabitumens..The following methods are used for microscopic analysis: microscopy, reflectance photometry, fluorescence photometry, micr
