13.1" Triassic Polished Petrified Wood Slab - Circle Cliffs, Utah

Triassic Polished Petrified Wood Slab - Circle Cliffs, Utah #244648

This is a 13.1" wide, polished slab of petrified wood from the Triassic Chinle Formation of Utah. It has polished on one side to a glossy finish and comes with a display stand.

It is part of an old collection I recently purchased with some unique pieces from unusual localities.

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.
