kivistuda
Kivistuda is a term that refers to the process of hardening or petrifying organic matter. This typically occurs over long geological timescales, where the original material, such as wood or bone, is gradually replaced by minerals. The process is a form of fossilization, and the resulting material is known as petrified wood or fossilized bone, respectively.
The mechanism behind kivistuda involves the slow infiltration of mineral-rich groundwater into the porous structure of
Factors influencing the rate and extent of kivistuda include the availability of minerals, the pH and temperature
