Chibcha Terrane
The Chibcha Terrane (Spanish: Terreno Chibcha, TCH), named after Chibcha, is the largest of the geological provinces (terranes) of Colombia. The terrane, the oldest explored domains of which date to the Meso- to Neoproterozoic, is situated on the North Andes Plate. The megaregional Romeral Fault System forms the contact of the terrane with the Tahamí Terrane. The contact with the Caribbean and La Guajira Terranes is formed by the regional Bucaramanga-Santa Marta Fault. The northeastern boundary is formed by the regional Oca Fault, bounding the La Guajira Terrane. The terrane is emplaced over the Río Negro-Juruena Province of the Amazonian Craton along the megaregional Eastern Frontal Fault System.
