4.8" Polished Petrified Wood (Araucaria) Stand-up - Brazil

This is a beautiful 4.8" wide section of 250 million year old petrified wood from Brazil. It comes from an ancient conifer of the genus Araucaria. One face has been polished to a glossy finish and the base has been cut flat for presentation. Petrified wood from Brazil is getting hard to come by due to recent export restrictions.

Petrified wood is the name given to wood that has been turned into stone (fossilized) through the process of permineralization. All of the organic matter becomes replaced by minerals, while much of the original structure such as tree rings in retained. For this to happen the wood needs to be buried in an environment both low in oxygen (preventing decomposition) and with flowing, mineral-laden water. The coloration is due to the various minerals that are present during fossilization. For example red colors are due to iron compounds, greens due to copper, etc.
