Evaporite Deposits of Bogota Area, Cordillera Oriental, Colombia

AAPG Bulletin, 1972
Four evaporite-bearing stratigraphic zones are known in Cretaceous strata of the Cordillera Oriental of Colombia north and east of Bogota. The easternmost and oldest zone is probably of Berriasian to Valanginian age. The next oldest is probably late Barremian to early Aptian in age. The third appears to be Aptian.

Pre-Cretaceous Sediments in Cordillera Oriental of Colombia

AAPG Bulletin, 1941
Although there are scattered references in the literature to exposures of rocks of Paleozoic age in the Cordillera Oriental of Colombia, the fact that they are widespread and probably represent a good portion of the upper Paleozoic has not generally been recognized.

The Magmatic Evolution of the Cordillera Oriental, Southeastern Peru

1984
Magmatism within the Central Andean Inner Arc of the Cordillera Oriental of southeastern Peru is characterized both by its episodicity (ca. 350, 270–250, 240–230, 180, 90–70 and 26–4 Ma) and its variable chemical/petrological signature. In both respects, marked contrasts are evident with the quasi-continuous and petrochemically unified subduction ...

A pliocene flora from the subachoque valley (Cordillera Oriental, Colombia)

Review of Palaeobotany and Palynology, 1990
Abstract A palynological and macrobotanical study was made of a 40 cm long peaty clay layer (SUBA 39 section) intercalated in fluvial deposits of Pliocene age from the Subachoque Valley, located at the northwestern border of the high plain of Bogota in the Cordillera Oriental of Colombia at an elevation of 2820 m above sea level. This has permitted a

Crustal and uppermost mantle velocity structure beneath the Cordillera Central and Cordillera Oriental, Dominican Republic

The oblique convergence between the Caribbean and North American plates produces the tectonic complexity of Hispaniola Island. The western region is characterized by high topography bounded by dominantly reverse and oblique-slip faults along the edges of the uplifted mountain ranges, while the eastern part is lower in elevation and no important active ...

Late Pliocene paleoecology of the Guasca Valley (Cordillera Oriental, Colombia)

Review of Palaeobotany and Palynology, 1993
Abstract Organic-rich layers intercalated in a Late Pliocene fluvial-lacustrine sediment sequence located at 2650 m elevation in the Guasca Valley (high plain of Bogota, Cordillera Oriental, Colombia) were analysed for plant micro- and macrofossils. Paleoenvironmental reconstructions indicate that a subandean forest (lower montane), at present found ...
