This is an impressive, 15.3" wide, polished, petrified wood round (Tanoak) from Swartz Canyon, Oregon. It's part of a large collection of petrified wood I recently purchased from an old collection that includes some exceptionally nice specimens from a variety of locations. This piece is nicely polished on one side and shows beautiful wood grain detail.

What Is Petrified Wood

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.
