Geoscience Ontology Description
Corresponding biogenic sedimentary material and biogenic sedimentary rock categories are not included based on the interpretation that biogenic sedimentary rock will be in a different category, e.g. carbonate sedimentary rock or organic rich sedimentary rock. Sediment composed of greater than 50 percent material of biogenic origin. Because the biogenic material may be skeletal remains that are not organic, all biogenic sediment is not necessarily organic-rich.
