Caribbean terrane
Geological province of Colombia
From Wikipedia, the free encyclopedia
The Caribbean terrane (Spanish: Terreno del Caribe, TC) is a geological province (terrane) of Colombia. The terrane, dating to the Late Cretaceous, is situated on the North Andes plate and borders the La Guajira, Chibcha and underlying Tahamí terrane along the regional Bucaramanga–Santa Marta Fault.[1] The terrane overlies the Tahamí, Arquía and Quebradagrande terranes along the Romeral fault system.[2][3]

Reinterpretation
A study performed by Mora Bohórquez et al. in 2017 showed no basement variation between the Chibcha terrane San Lucas basement underlying the Lower Magdalena Valley (VIM) and the SNSM basement to the east of the Santa Marta fault. The authors redefined the contacts between the different terranes, using the names Calima terrane for the coastal portion of the Caribbean terrane (San Jacinto and Sinú fold belts) and Tahamí–Panzenú terrane for the Tahamí terrane.[4]
