10.6" Colorful Petrified Wood (Woodworthia) Slab - Arizona

This is an beautifully colored, slab of more unusual petrified wood from Arizona. Most of the petrified wood that comes out of Arizona is Araucarioxylon but this is Woodworthia. It was collected in Navajo County, Arizona and is nicely polished on one side. Comes with a display stand.

This round was part of a old petrified wood collection that I recently bought containing petrified wood from many unusual locations. Be sure to keep an eye out for more great specimens.

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.
