récupighigenous

Récighigenous is a term used in geology and paleontology to describe fossils or mineral deposits that are found in rock formations of a different age than their original formation. This typically occurs through geological processes such as erosion, transportation, and redeposition. For example, a fossil that formed in the Cretaceous period might be found within a sedimentary layer deposited in the Tertiary period. The original rock containing the fossil was eroded, and the fossil-rich sediment was then carried and deposited in a new location, becoming incorporated into a younger geological strata.

The identification of récighigenous material is important for accurate geological dating and understanding past environments. When scientists encounter récighigenous fossils or minerals, they must distinguish them from the indigenous life or minerals of the host rock to avoid misinterpreting the age of the deposit. This process often involves detailed examination of the fossil's preservation state, the surrounding matrix, and other associated geological evidence. The presence of récighigenous material can indicate periods of significant geological activity, such as uplift and erosion, followed by sedimentation. It can also provide clues about ancient drainage systems and the provenance of sediments.
