Petrified wood is silicified asbestos. When crocidolite (blue asbestos) in a rock is subject to metasomatism by a hot silicate-rich solution, it transforms into a cryptocrystalline quartz aggregate composed of silica but retains its asbestos fibrous structure. It is called petrified wood because it looks like a piece of wood (Fig. 16).
