How wood gets petrified
Petrified wood is created when a living tree falls into a stream, it gets caught and gets buried under sand and mud . Through time it gets buried deeper and deeper under the mud.It gets cut of from oxygen and ceases rotting. Silica in the ground water infiltrates the wood and through a chemical reaction replaces the organic mater with quartz crystals. The log is petrified. Subsequent erosion of the surrounding rock re-exposes the petrified log. Continued erosion undercuts the log causing it to crack into segments . This wood is thousands of years old
