Petrified wood (from the Greek root petro meaning rock or stone; literally wood turned into stone) is the name given to a special type of fossilized remains of terrestrial vegetation. It is the result of a tree or tree-like plants having completely transitioned to stone by the process of permineralization.rtificial petrified wood has been produced in a Washington laboratory. In the process, small cubes of pine are soaked in an acid bath for two days, then in a silica solution for another two. The product is then cooked at 1400 Â°C in an argon atmosphere for two hours.
The Rock &Gem magazine, August 2010 issue, had an article about collecting at the DoBell Ranch which was in the Holbrook area. We drove east from Holbrook to the northern entrance to the Petrified Forest National Park. At the entrance I was asked by the attendant if I had any petrified wood.he original wood had been buried in the long ago past and the wood was replaced by silica with trace minerals. Those trace minerals produced the rainbow of colors that are displayed in the petrified wood. It is amazing to look at the end of a petrified log two foot in diameter and view the various color showing.
