A model is suggested for Io's surface composition involving evaporite salt deposits, rich in sodium and sulfur. According to this model, these deposits were produced as a result of the migration of salt-saturated aqueous solutions to Io's surface from a warm or hot interior followed by loss of the water to space. This model satisfies cosmochemical constraints based on Io's initial composition, current density, and thermal history. Salt-rich assemblages are easily derivable from the leaching of…

TLDR
The Orgueil meteorite, the principal object of the present investigation, fell a t 8 P.M. on May 14, 1864 and was observed to fall, while the appearance of the luminous meteor, the subsequent detonations and the fall were observed by the local residents.
