The Tahamí or Tahamí-Panzenú Terrane is one of the geological provinces (terranes) of Colombia. The terrane, dating to the Permo-Triassic, is situated on the North Andes Plate. The contact with the Chibcha, Arquía and Quebradagrande Terranes is formed by the megaregional Romeral Fault System. A tiny terrane is located at the contact with the Quebradagrande Terrane; Anacona Terrane.
Tahamí Terrane is enclosed by the Bucaramanga-Santa Marta Fault (orange), northernmost Oca Fault (white) and Romeral Fault System (violet)
The North Andes Plate or North Andes Block is a small tectonic plate (microplate) located in the northern Andes. It is squeezed between the faster moving South American Plate and the Nazca Plate to the southwest. Due to the subduction of the Coiba and Malpelo plates, this area is very prone to volcanic and seismic activity, with many historical earthquakes.
