Silicified Wood

Florida Geological Survey Logo

Although silicified wood is not of mineral origin, the original wood has been replaced by silica (SiO2) in solution or more rarely by clay minerals. Often the fine details of the original tree bark are preserved. Silicified wood is commonly unearthed in mines.
