Pumice

Pumice is a type of extrusive volcanic rock, produced when lava with a very high content of water and gases is discharged from a volcano As the gas bubbles escape, the lava becomes frothy When this lava cools and hardens, the result is a very light rock material filled with tiny bubbles of gas Commonly it is light-colored, indicating that it is a volcanic rock high in silica content and low .Silica gossan as a prospective guide for amethyst geode , Silica gossan as a prospective guide for amethyst geode deposits in the Ametista do Sul mining district, Paraná volcanic.
