The Une Formation (Spanish: Formación Une, Kiu) is a geological formation of the Altiplano Cundiboyacense, Eastern Ranges of the Colombian Andes. The predominantly sandstone formation dates to the Middle Cretaceous period; Albian to Cenomanian epochs and has a maximum thickness of 1,100 metres (3,600 ft).
Etymology[]
The formation was defined in 1957 by Hubach after Une, Cundinamarca.[1]
Description[]
Lithologies[]
The Une Formation has a maximum thickness of 1,100 metres (3,600 ft) and is characterised by a sequence of sandstones.[2] Fossils of Heminautilus etheringtoni have been found in the Une Formation.[3]
Stratigraphy and depositional environment[]
The Une Formation, part of the Villeta Group, overlies the Fómeque Formation and is overlain by the Chipaque Formation. The age has been estimated to be Albian-Cenomanian. Stratigraphically, the formation is time equivalent with the Simijaca, , Caballos and Pacho Formations. The formation has been deposited in a near shore deltaic environment.[4]
Outcrops[]
The Une Formation is apart from its type locality, found on the Sumapaz Páramo.[2]
