Pumice clast behaviour in a boiling water context: sedimentological implications

Pumice clasts present in some detritic sedimentary sequences suggest that they have a density exceeding that of water during transport and accumulation. Because these clasts usually have a density that does not exceed 1g/cm3 and float on water, their behaviour suggests a sinking process to enable th...
