6.3" Polished Petrified Wood (Araucaria) Section - Madagascar

This is a 6.3" wide and 1.9" thick polished section of petrified Araucaria (conifer) wood from Ambilobe, Madagascar. This 220 million year old petrified wood has been sliced and polished on both sides allowing the stunning inner wood detail to easily be seen. The sides of this piece have an excellent bark pattern.

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.
