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 Hubach in 1931 as part of the Usme Formation and redefined and named in 1963 by Julivert after the La Regadera Reservoir.¹

Description

Lithologies

The Regadera Formation consists mainly of quartz arenitic sandstone and conglomerates with some shale beds.¹²

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 Echitriporites trianguliformis var. orbicularis, Nothofagidites sp. and Multiporopollenites pauciporatus, to be Middle to Late Eocene.³ The depositional environment has been interpreted as a braided river setting.⁴

Outcrops

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

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 Sisga.¹ In the Tunjuelo River valley, the Regadera Formations is present in the escarpments on the river banks.⁵
