Concentrate deposit

from Wikipedia, the free encyclopedia

A concentrate deposit is an enrichment of mostly unconnected (disarticulated) fossils with different conservation status. The further subdivision can be made on the basis of differences in sedimentation rates , the degree of transport secretion and the course of early diagenesis . A distinction is made between the concentrate storage facilities and the preservation storage facilities. These fossil deposits are characterized by an exceptionally good fossil conservation.

species

In principle, a distinction is made between three types of concentrate storage facilities:

Condensates

Condensates are formed with little or no net sedimentation. Examples are continental cave clay on the mainland, the terrestrial deposit space terrestrial area, submarine cave deposits and condensation horizons.

Soap

Soaps are enrichments that can be traced back to sedimentary transport. Examples are bonebeds (enrichment of bones and teeth), Schill (enrichment of the shell remains of mussels (Bivalva) or arm pods (Brachiopoda)) and amber .

Concentrate traps

Concentrate traps are created when animal and plant remains are washed into cavities. These include column fillings and grave tunnel fillings.
