Description
Petrified wood (from Ancient Greek πέτρα meaning ‘rock’ or ‘stone’; literally ‘wood turned into stone’) is the name given to a special type of fossilized remains of terrestrial vegetation. Petrifaction is the result of a tree or tree-like plants having been replaced by stone via a mineralization process that often includes permineralization and replacement. The organic materials making up cell walls have been replicated with minerals (mostly silica in the form of opal, chalcedony, or quartz).
