OSAC Lexicon
The OSAC Lexicon is a compendium of forensic science terms and definitions. This terminology tool was created to help bring consistency and understanding to the way terms are used by the various forensic science. Use of the OSAC Lexicon does not replace the need to reference the original published source.
The terms and definitions in the OSAC Lexicon come from the published literature, including documentary standards and technical reports. It is continually updated with the latest work from OSAC units, as well as terms from newly published documentary standards and standards elevated to the OSAC Registry.
Gradually terms are evaluated and harmonized by the OSAC to a single term. This process results in an OSAC Preferred Term. An OSAC Preferred Term is a term, along with its definition, that has undergone review and evaluation by the FSSB Terminology Task Group and has been approved by the FSSB. The FSSB recommends that subcommittees use OSAC Preferred Terms when drafting standards.
The OSAC Lexicon should be the primary resource for terminology and used when drafting and editing forensic science standards and other OSAC work products.

segregations within the soil matrix with different color or shades of color interspersed with the dominant (matrix) color.
Discussion—The NCSS reserves the term mottles for color variations that cannot be associated with compositional properties of the soil, whereas color variations attributable to compositional variations are designated with distinct terms (redoximorphic features, concentrations, ped coatings, etc.). However, in a forensic examination mottling is often used to describe any color contrast within a soil aggregate, regardless of its origin.
