Sorting Nomenclatural Assortment

richard L. Threet

ABSTRACT

While "assorted" connotes miscellany, and "sorted" (graded) connotes singularity, the literature of sedimentology is confused occasionally by such unnecessary terms as "well-assorted" (intended to mean "well-sorted") and "unassorted" (which ought to mean not assorted, hence "sorted," but which is intended to mean "poorly-sorted"). Further confusion comes about in engineering geology and engineering literature by use of "uniformly-graded" (intended to mean uniform frequency distribution of various textural grades, hence "poorly-sorted"). To avoid ambiguity, various derivatives of "assorted" and "to assort" should be abandoned; "uniformly-graduated (texture)" may be an appropriate term for mechanically stable engineering soils of high density.
