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.[1] The contact with the Caribbean and La Guajira Terranes is formed by the regional Bucaramanga-Santa Marta Fault.[2] The northeastern boundary is formed by the regional Oca Fault, bounding the La Guajira Terrane.[3] The terrane is emplaced over the Río Negro-Juruena Province of the Amazonian Craton along the megaregional Eastern Frontal Fault System.[4][5]
