Albian

From Wikipedia, the free encyclopedia

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

Albian is a term proposed in 1842 by Alcide d'Orbigny for that stage of the Cretaceous system which comes above (later than) the Aptian and below (before) the Cenomanian,^[1] the last stage of the Early Cretaceous. Its 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.
