Very Rare Petrified Oak Hardwood | Ochoco Mountains, Oregon
This Super Rare Petrified Oak wood was collected on private land in the Ochoco Mountains, Oregon. It was polished to a brilliant shine on one side showing off intricate growth rings and fine layers. This is only one of six slices in existence.
Permian, Triassic, Jurassic and Eocene
Dimensions: approx 19.5" x 12.25" specimen slab .75" approximate thickness
Petrified Wood formed when the original trees and branches were rapidly buried under sediment and were initially preserved due to a lack of oxygen some 50 million years ago. Petrifaction occurs when water that contains inorganic minerals, such as calcium carbon-ate or silica, passes slowly through the organic wood.
As the original wood’s lignin and cellulose decay away, its original cellular structure is duplicated and replaced by these inorganic minerals. Elements such as manganese, iron and copper in the water and sediment during the petrification process give petrified wood a variety of color ranges.
The Ochoco Mountains are a mountain range in central Oregon in the United States, located at the western end of the Blue Mountains. They were formed when Permian, Triassic, and Jurassic rocks were slowly uplifted by volcanic eruptions to form the Clarno Formation. Wikipedia
