Description	Extremely arsenic-rich acid mine waters have developed by weathering of native arsenic in a sulfide-poor environment on the 10th level of the Svornost mine in Jachymov (Czech Republic). Arsenic rapidly oxidizes to arsenolite (As2O3), and there are droplets of liquid on the arsenolite crust with high As concentration (80,000-130,000 mg.L-1), pH close to 0, and density of 1.65 g.cm(-1). According to the X-ray absorption spectroscopy on the frozen droplets, most of the arsenic is As(III) and iron is fully oxidized to Fe(III). The EXAFS spectra on the As K edge can be interpreted in terms of arsenic polymerization in the aqueous solution. The secondary mineral that precipitates in the droplets is kaatialaite [Fe3+(H2AsO4)(3).5H(2)O]. Other unusual minerals associated with the arsenic lens are behounekite [U4+(SO4)(2).4H(2)O], stepite [U4+(AsO3OH)(2).4H(2)O], vysokyite [U4+[AsO2(OH)(2)](4).4H(2)O], and an unnamed phase (H3O)(+)(2)(UO2)(2)(AsO4)(2).nH(2)O.
