In geology, petrification (from Ancient Greek πέτρα (pétra) 'rock, stone') is the process by which organic material becomes a fossil through the replacement of the original material and the filling of the original pore spaces with minerals.
Scientists have attempted to duplicate the process of petrification of wood, both to better understand the natural petrification process [2] and for its possible use as a ceramic material. [15] Early attempts used sodium metasilicate as a source of silica, but tetraethyl orthosilicate has proven more promising.

In geology, silicification is a petrification process in which silica-rich fluids seep into the voids of Earth materials, e.g., rocks, wood, bones, shells, and replace the original materials with silica (SiO 2). Silica is a naturally existing and abundant compound found in organic and inorganic materials, including Earth's crust and mantle ...
