6" Red And Yellow Jasper Replaced Petrified Wood Bookends - Oregon

This is a very unique pair of bookends made from jasper replaced petrified wood from Marsdon Ranch, Oregon. They are 6.0" and 5.8" tall, respectively and are polished on one face to show detail. They are also felt covered on two end faces to protect the surfaces they come in contact with. The jasper replacement left a beautiful coloration with hues of red and yellow but unfortunately all but destroyed the detail that would allow for the type of tree to be identified. Some grain pattern is still visible.

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