Blue Opalized Petrified Wood is a fossil which the wood from the tree has been replaced by opal silicate over a long period of time. The petrified wood was formed when tree material (wood) is buried by sediment. The ground water which was rich in dissolved copper, iron, manganese, silica and Opal minerals flowed through the sediment and these minerals gradually replaced the wood. The presence of Copper and Cobalt gives the mineral a blue color and Silica gives it a white and gray color. Manganese Oxides and carbon give it a black color. The source deposit found on the steep slopes of Mt. Blue Opalized Petrified Wood is often used as a gemstone for jewellery or display mineral specimen by collectors.
