secule Geol. Obsolescent.|ˈsɛkjuːl| [f. L. sæculum age, generation.] A period of geological time corresponding to a stratigraphical zone; = moment n. 2 d.
1903A. J. Jukes-Browne in Geol. Mag. X. 37 The term hemera may, however, be occasionally convenient to signify the duration of a subzone, as age signifies the duration of a stage, but if we want to avoid confusion we must not speak of the hemera of a zone. For this another word should be coined..I would suggest that the Latin word seculum will furnish us with ‘secule’ which finds an actual French equivalent in siècle. 1933W. J. Arkell Jurassic Syst. Gt. Brit. i. 21 Several hemeræ may be contained in one secule or zone-moment. 1956Amer. Jrnl. Sci. CCLIV. 459 Schindewolf reasserts..his extreme view..that the zone as conceived by Oppel was a purely chronological notion and that the term zone should be used only as a time term (= secule). 1969[see moment n. 2 d]. |
