Do you mean “quaternary” in geology, math, chemistry, biology, or something else? Short definitions of common meanings:
- Quaternary (geology): the most recent geologic period (from 2.58 million years ago to present), marked by repeated glaciations and the rise of Homo sapiens.
- Quaternary (numeral system): base‑4 positional number system using digits 0–3.
- Quaternary (protein structure): the arrangement/assembly of multiple polypeptide subunits in a multi‑subunit protein.
- Quaternary ammonium: a positively charged nitrogen atom bound to four organic groups (a quaternary ammonium cation).
- Quaternary sector (economics): the knowledge/information services part of the economy (R&D, IT, education).
