9.1" Petrified Wood (Poplar) End-Cut - Vantage, Washington

This is a polished end-cut of a petrified wood log collected near Vantage, Washington. It's identified as being Poplar and would be Miocene in age from the Wanapum Basalt Formation. It's 9.1" wide, weighs about 6 lbs and one face has been polished to a mirror like finish. It has wonderful wood grain detail preserved. It comes out of an old collection of petrified wood that we recently purchased that has some rather unusual pieces from rare locations.

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.
