10.4" Triassic Petrified Wood (Araucaria) Log - Circle Cliffs, Utah

 
 
This is a beautiful log of petrified wood (Araucaria)from the Circle Cliffs, Utah. Araucaria is an extinct conifer from the same family as modern Monkey Puzzle trees. This log is polished on one end to highlight the grain and inclusions. This beautiful specimen even has a preserved knot.

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.
