7.2" Polished Petrified Wood (Conifer) Slab - Texas

This is a 7.2" wide, polished slab of petrified wood from Hen Mountain in Brewster County, Texas. The wood was found in a Miocene alluvial deposit, so it may be older than the formation it was found in. This comes from a collection of petrified wood I recently bought which includes some rare types from unusual locations.

It has been cut flat on both sides and polished to a glossy finish on one. 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. 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.
