| dc.description | The origin of alunite and natroalunite from a kaolin deposit (Equivocada Mine, Rio Negro Province) has been studied. Chemical analysis showed that alunite is K<sub>0.89</sub> and natroalunite Na<sub>0.97</sub>, in agreement with X ray diffraction data. The high contents of minor elements in alunite, especially Ba and Sr are compatible with a hydrothermal origin in contrast to natroalunite whose very low values suggest a secondary origin. Alunite has a δ<sup>34<sup/>S = +15.9‰ and a δ<sup>18</sup>O = +12.9‰, while in natroalunite these values are -5.8‰ and +19.0‰ respectively. δ<sup>34<sup/>S values suggest that alunite formed from a hypogenic process of hydrothermal origin whereas natroalunite is probably related to a supergen origin. The occurrence of alunite in veins crosscutting the other minerals, indicates that it was the last mineral to crystallize. | - |
