| description | The Central Cordillera of Colombia consists of several tectonostratigraphic terrains that have not been fully recognized yet. To the east of San Jerónimo Fault are found the Chibcha, Tahamí, Panzenú (Puquí) and Anacona (Caldas) terrains with continental basement, and between the Romeral and the Cauca fault systems the Quebradagrande, Amagá-Sinifaná, Heliconia and Arquía terranes, mostly oceanic, are found. The Chibcha terrain is formed by a Grenvillian basement covered by Lower Paleozoic sediments that suffered a slight metamorphism, while in the Tahamí the metamorphism is Late Permian to Triassic, indicating that it was formed within the collision zone of Pangea but rather in the Paleopacific margin of Pangea as part of the Terra Australis Orogen. The metamorphism in the Panzenú Terrain is somewhat older, Carboniferous. The Anacona Terrain presents Devonian metamorphism and was not affected by the Triassic metamorphism that affected the Tahamí, indicating that it had not been amalgamated yet during the Triassic orogeny. A number of narrow belts of allochtonous rocks were accreted after Mid-Cretaceous times to the Tahamí Terrane which are from east to west: the Quebradagrande Complex, the Sinifaná low-grade metasedimentary rocks and the Amagá Granite (Amagá-Sinifaná Terrane), the ophiolitic rocks of Heliconia and the Arquía Complex. All of them are located between the systems of faults Cauca and Romeral. |

La Cordillera Central de Colombia está compuesta por varios terrenos tectonoestratigráficos que no han sido aún bien reconocidos. Al este de la Falla San Jerónimo se encuentran terrenos continentales como los terrenos Chibcha, Tahamí, Panzenú (Puquí) y Anacona (Caldas), mientras que entre los sistemas de Falla de Romeral y de Cauca se encuentran los terrenos Quebradagrande, Amagá-Sinifaná, Heliconia y Arquía, predominantemente de carácter oceánico. El terreno Chibcha incluye un basamento grenvilliano con sedimentos del Paleozoico Inferior, que sufrieron un leve metamorfismo, mientras que el metamorfismo del terreno Tahamí parece ser Pérmico muy tardío a Triásico, evidenciando que se formó en la margen paleopacífica de Pangea, como parte del orógeno de Terra Australis, más bien que en la zona de colisión continental. El terreno Panzenú sufrió un metamorfismo Carbonífero, anterior al del Tahamí. El terreno Anacona presenta edades de metamorfismo Devónicas y no fue afectado por el metamorfismo Triásico, indicando que aún no se había amalgamado al terreno Tahamí durante la orogenia Triásica. Un conjunto de delgadas franjas alóctonas parece haberse amalgamado después del Cretáceo Medio al Tahamí, y está constituido de oriente a occidente por las rocas del Complejo Quebradagrande, las Metasedimentitas de Sinifaná y el Stock de Amagá (terreno Amagá- Sinifaná), las rocas ofiolíticas de Heliconia y las rocas metamórficas del Complejo Arquía. Todas ellas se encuentran localizadas entre los sistemas de fallas Cauca y Romeral.
