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. 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.
