5.4" Green Petrified Wood Bookends - Hampton Butte, Oregon
This is a very unique pair of bookends made from green petrified wood from Hampton Butte, Oregon. Portions of this petrified wood are jasper replaced. They are approximately 5.4" tall, 5.4" wide and 1.75" thick. They are polished to a mirror like finish on one face and two of the sides lined with felt.
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.
