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, Aguardiente, Caballos and Pacho Formations. The formation has been deposited in a near shore deltaic environment.^[4]

Type locality of the Une Formation to the south of the Bogotá savanna

The Une Formation is apart from its type locality, found on the Sumapaz Páramo.^[2]
