8.7" Polished Petrified Wood (Willow) Round - Washington

This is a 8.7" wide, polished round of Miocene aged petrified wood (Willow) from Kittitas County, Washington. The polishing allows for the beautiful wood detail including tree rings to easily be seen. This is part of a collection of petrified wood rounds I recently purchased that include some material from unusual locations, many of which are either no longer accessible or unproductive.

It comes with an acrylic display stand.

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.
