title: PLANETARY SCIENCE: Enhanced: Salty Old Rocks.
abstract: Small grains of halite in meteorites are generally interpreted as a sign of the former presence of water. In his Perspective, Ott discusses the unexpected discovery of halites in relatively highly metamorphosed meteorites. According to the age determined by Whitby et al. for halite crystals in one of these meteorites, they are among the oldest known materials in the solar system.
