Biologicals
Biologicals, as used here, refers to those particles that originate from living organisms. They are
identified by the combination of shape and optical properties that confirm their origin. Many of these
materials; such as diatom casts, siliceous phytoliths, and fossils; are not carbon-based in their final form.
