fossilisoitumisen
Fossilisoitumisen, the Finnish term for fossilization, refers to the complex process by which organic remains are preserved in rock. This transformation occurs over vast geological timescales, typically involving the gradual replacement of original organic material with minerals. The most common type of fossilization is permineralization, where groundwater seeps into the porous structures of bone, shell, or wood, depositing dissolved minerals like silica, calcite, or pyrite. These minerals then crystallize, filling the empty spaces and solidifying the remains.
Another significant process is replacement, where the original organic material is dissolved and simultaneously replaced by
For fossilisoitumisen to occur, several conditions are generally necessary. Rapid burial is crucial to protect the
