41	+*SASR	Siliciclastic argillaceous sediment and rock - In the Rock Classification Scheme, this class includes siliciclastic argillaceous sediment and siliciclastic argillaceous rock.

42	+*SNCS	Sedimentary rock and sediment composed of non-carbonate salts - In the Rock Classification Scheme, this is a non-genetic term for what are commonly called evaporite minerals.

A definition based on a greater than 50% volumetric abundance of organic matter is not possible because historically the definitions of sediments and sedimentary rocks rich in organic-matter have been based on their quality as fossil fuels.
