fossiilileide
Fossiilileide is a Finnish term used to describe a type of fossilized mudstone deposited in sea environments, particularly in shallow marine settings. This type of rock is characterized by its fine-grained texture and high organic content, rich in plant and animal remains. The term is derived from the Finnish words for "fossil" and "mud," which accurately reflects the composition of the rock.
Fossiilileide typically forms through the rapid sedimentation of organic-rich mud in low-energy environments such as shorelines,
Geochemically, Fossiilileide often exhibits high levels of organic carbon, sulfur, and other elements associated with marine
Due to its high organic content and variety of fossils, Fossiilileide is considered an important geological
