5.4" Petrified Wood (Sequoia) Stand-up - Rogers Mountain, Oregon
This is a beautiful, free-standing petrified wood section with great wood detail. This section of 20 million year old, petrified wood (Sequoia) from Rogers Mountain, Oregon has been cut and polished to a glossy finish. It's 5.4" tall by 3.7" wide, has a flat cut base and displays wonderfully on any flat surface.
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.
