Usage:
/Sur series [informal] (CA)
[When referring to the Sur series of Trask (1926), please use informally. Or, see NACSN (2021, Art. 29a, 38) for suggestions on replacement terms. The practice of employing "Series" for lithostratigraphic or lithodemic nomenclature is now regarded as improper (ACSN, 1961, 1970; NACSN, 1983, 2005, 2021). The term "Series" is applied formally only to chronostratigraphic units.]
