Silification is one of a number of methods by which petrification, or petrifaction, occurs. Wood is the most common find when it comes to petrification. It occurs when organic matter becomes saturated with silica. Combined with a neutral or slightly acidic pH, as well as temperatures and pressure that are mirror shallow sedimentary environments, it is possible for silification to take place in approximately 50,000 years or less.
