Summary: Petrified fossils result from permineralization, the replacement of once-living matter by minerals. Solutions containing silicates, carbonates, iron or other minerals seep into the gaps and spaces between the cells, first encasing the cells and eventually replacing the cells themselves.
Petrification is the process through which organic materials are transformed into stone-like structures, primarily through the replacement of the original material with minerals. This process is a key aspect of fossil preservation, as it allows for the detailed replication of the original biological features in a mineralized form, providing ...
In geology, petrifaction or 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.
