The Chibcha terrane, named after Chibcha, is the largest of the geological provinces of Colombia. The terrane, the oldest explored domains of which date to the Meso- to Neoproterozoic, is situated on
Chibcha terrane is enclosed by the Bucaramanga–Santa Marta Fault (orange), northernmost Oca Fault (white), Eastern Frontal Fault System (yellow) and Romeral fault system (violet)
The Chibcha terrane stretches out across the Eastern Ranges, but also includes the Serranía de San Lucas to the west and triangular Sierra Nevada de Santa Marta to the north
The triangular Sierra Nevada de Santa Marta, east and south of Santa Marta is bound to the west by the Santa Marta Fault (BSF) and to the north by the Oca Fault. The Cesar-Ranchería Basin is visible on the lower right.

…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…
