Albian


Albian

Albian (French "Albion", from Alba = Aube in France) is a stage of the Cretaceous period.

Albian is a term proposed in 1842 by A. d'Orbigny for that stage of the Cretaceous system which comes above (later) the Aptian and below (before) the Cenomanian (Pal. France. Cret. ii.). Approximate time range is 112.0 ± 1.0 Ma to 99.6 ± 0.9 Ma (million years ago).

The following representatives of the Albian stage are worthy of notice: the gaize and phosphatic beds of Argonne and Bray in France; the Flammenmergel of North Germany; the lignites of Iltrillas in Spain; the Upper Sandstones of Nubia, and the Fredericksburg beds of North America.
