A multi-technique study of altered granitic rock from the Krunkelbach Valley uranium deposit, Southern Germany

Abstract

<p>A multi-technique elemental and microphase analysis of altered granitic rock from the Krunkelbach Valley uranium deposit, Black Forest, Southern Germany.</p>

Application of transition-edge sensors for micro-X-ray fluorescence measurements and micro-X-ray absorption near edge structure spectroscopy: a case study of uranium speciation in biotite obtained from a uranium mine

“…Therefore, it is used for the analysis of trace amounts of U adsorbed on minerals in environment samples. [26][27][28][29] However, a problem of U speciation occurs in granitic rocks and mica samples when XAS is performed. When Rb coexists in a sample, the Rb Kα fluorescent X-ray at 13.395 keV interferes with the U Lα 1 fluorescent X-ray at 13.615 keV due to the low energy resolution of solid-state detectors such as the Ge solid-state detector (Ge-SSD) or the silicon drift detector (SDD).…”
