Large 11 inch Petrified Wood Slab - Madagascar
This is a large, richly colored petrified wood slab mined near Ambilobe, Madagascar. It is approximately 11x9 inches and one side has been polished to a mirror like finish. The polishing was done by one of the best polishers out there, and doesn't have scuff marks or dull spots like lower quality material. The color variety and detailed wood structure make this specimen second to none.
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.
