The state or condition of being petrified.

That which is petrified; popularly, a body incrusted with stony matter; an incrustation.

the process of turning some plant material into stone by infiltration with water carrying mineral particles without changing the original shape

a rock created by petrifaction; an organic object infiltrated with mineral matter and preserved in its original form

a fossilization process whereby inorganic matter dissolved in water completely replaces original organic mater, converting it to a stony substance.

a type of preservation in which mineral matter infills intercellular spaces and replaces the cell walls; compare to permineralization and silification

The preservation of organisms where a mineral in-fills intercellular and intracellular cavities and also replaces the organic material of cell walls.

see Permineralization.

or petrification: the process of turning organic materials into rock by the replacement of the organic matter with minerals. [AHDOS

In geology, petrifaction or petrification is the process by which organic material is converted into stone or a similar substance. It is approximately synonymous with fossilization. Petrified wood is the most well known result of this process.
