Opalised wood or petrified wood is a variety of opal that has replaced fossil wood. When the wood becomes petrified, its original mold remains intact, but an entire new substance takes the place of what was once wood. When the mineral replacement of the wood is Chalcedony or Opal, the substance is also called 'Silicified Wood'.
