Petrified Wood

Petrified Wood is a fossil in which the organic remains of wood have been replaced by minerals and effectivelty turned to stone. This petrification process generally results in a Quartz Chalcedony mineralization.

For living wood to be transformed into petrified wood it must have been buried in an oxygen-free environment. Exposure to mineral-rich water absorbed by the tissues replaces the organic plant matter with inorganic stone.
The structure and appearance of the orginal wood, (even the tree rings) are well preserved, even at the microscopic level. This process can occur in less than one thousand years.
