4" Petrified "Mustard Wood" (Conifer) Slice - New Mexico

This is a 4" wide section of petrified "mustard wood" from San Juan County, New Mexico. Under magnification, the grain detail and mineral replacement are truly fascinating. One side has been polished to a glossy finish while the opposite side has been cut but not polished.

It comes with an acrylic display stand.

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.
