Abstract
Long-distance host-independent virus dispersal is poorly understood, especially for viruses found in isolated ecosystems. Todemonstrate a possible dispersal mechanism, we show that bacteriophage T4, archaeal virus Sulfolobus spindle-shaped virus Kamchatka, and vaccinia virus are reversibly inactivated by mineralization in silica under conditions similar to volcanic hotsprings. In contrast, bacteriophage PRD1 is not silicified. Moreover, silicification provides viruses with remarkable desiccationresistance, which could allow extensive aerial dispersal.
