Organic rich (sediment)

Keyword Definition

Sediment with color, composition, texture and apparent density indicating greater than 50 percent organic content by weight on a moisture-free basis.


The broader relation from organic rich sediment to biogenic sediment is based on the inference that organic rich material is always biogenic in origin. Biogenic is a broader category because not all biogenic materials are organic rich, for example shells or phosphatic bone.
