Despite the ever-increasing understanding of the genesis and stability of Au-bearing nanoparticles, it is still unknown how they behave when exposed to hydrothermal fluids. Here, we study the nanostructural evolution of Au\u2013Ag nanoparticles hosted within Co-rich diarsenides and sulfarsenides of a natural hydrothermal deposit. We use high-resolution transmission electron microscopy to provide a singular glimpse of the complete melting sequence of Au\u2013Ag nanoparticles exposed to the hydrothermal fluid during coupled dissolution\u2013precipitation reactions of their host minerals. The interaction of Au\u2013Ag nanoparticles with hydrothermal fluids at temperatures (400\u2013500 \u00baC) common to most hydrothermal gold deposits may promote melting and generation of Au\u2013Ag nanomelts. This process has important implications in noble metal remobilization and accumulation during the formation of these deposits.<\/p>\n\n\n\n<p>----------------------------------------------------------------------------------------------------------<\/p>\n\n\n\n<p><strong>To Cite this article:<\/strong> Dom\u00ednguez-Carretero, D., Gonz\u00e1lez-Jim\u00e9nez, J.M., Proenza, J.A., Villanova-de-Benavent, C., Llovet, X., &amp; Garcia-Casco, A.
