Abstract

Language:

Na–H3O jarosite was synthesized hydrothermally at 413 K for 8 days and investigated using single-crystal X-ray diffraction (XRD) and electron microprobe analysis (EMPA). The study aimed to elucidate the crystal structure and chemical composition of the synthetic jarosite, which is relevant to both terrestrial and extraterrestrial environments. The chemical composition of the studied crystal was determined to be [Na0.57(3)(H3O)0.36(H2O)0.07]A Fe2.93(3)(SO4)2(OH)6, revealing the occupancy of sodium and hydronium ions within the crystal lattice. Additionally, the findings contribute to understanding the temperature-induced changes in jarosite stability in planetary settings, as these changes can mimic compositional alterations. Results indicate that this synthetic phase provides significant insights into the formation and stability of jarosite minerals under low-temperature conditions and further support the identification of jarosite group minerals on Mars. The study outlines the potential for using X-ray diffraction methods to uncover structural details of complex minerals, offering implications for future research in mineralogy and planetary geology.
