petrifikaation
Petrification, sometimes rendered as petrifikasjon in some languages, is the natural process by which organic material is preserved as stone through mineralization. In geology and paleontology, petrification refers to the conversion of formerly living tissue into rock by the infiltration and replacement of organic material with minerals carried by water, most commonly silica (as quartz) or calcium carbonate. The result is a fossil that retains fine cellular structure and morphology of the original specimen.
The principal mechanisms are permineralization, whereby mineral-rich fluids fill pore spaces and cavities without destroying the
Petrification requires rapid burial to protect remains from decay, and groundwater rich in dissolved minerals. It
Petrification is one form of fossilization; other processes include carbonization, molds and casts, and preservation in
