The Regadera Formation (Spanish: Formación Regadera, E2r, Tpr) is a geological formation of the Bogotá savanna, Altiplano Cundiboyacense, Eastern Ranges of the Colombian Andes. The predominantly sandstone and conglomeratic formation, with pink shale beds intercalated, dates to the Paleogene period; Middle to Late Eocene epoch, and has a maximum thickness of 765 metres (2,510 ft).
Etymology[]
The formation was first described by in 1931 as part of the Usme Formation and redefined and named in 1963 by after the .[1]
Description[]
Lithologies[]
The Regadera Formation consists mainly of quartz arenitic sandstone and conglomerates with some shale beds.[1][2]
Stratigraphy and depositional environment[]
The Regadera Formation overlies the Bogotá Formation and is overlain by the Usme and Tilatá Formations. The age has been estimated, based on palynological data of , and , to be Middle to Late Eocene.[3] The depositional environment has been interpreted as a braided river setting.[4]

The Regadera Formation is apart from its type locality in the synclinal of Usme, the valley of the Tunjuelo River, found in the synclinal of .[1] In the Tunjuelo River valley, the Regadera Formations is present in the escarpments on the river banks.[5]
