the Jurassic volcanic rocks covering the Santander Massif were exhumed during the latest Cretaceous to early Paleocene. Outcrops The northernmost outcrop of the Noreán Formation is found in Chimichagua, Cesar. In Cesar, outcrops occur south of the village of Saloa and around the town of Pailitas, east of Tamalameque and Pelaya and west of La Gloria, in the western part of Morales, Bolívar, north and east of Aguachica where its type locality is situated, in the Serranía de San Lucas, where the urban center of Santa Rosa del Sur rests on top of the formation, in the west of San Pablo, Bolívar, and in the western part of Cantagallo, Bolívar. Regional correlations In the Santander Massif, the Noreán Formation has been correlated to the Jordán Formation, while in the Serranía de San Lucas the formation correlates with and is partly overlying the Morrocoyal Formation. In the Sierra Nevada de Santa Marta of northern Colombia, the Noreán Formation is considered equivalent with the Guatapurí Formation, the Corual and Los Indios Formations and the ignimbrite complexes of Caja de Ahorros, La Paila and La Piña. In the Serranía del Perijá to the east of the extent of the formation, the Noreán Formation correlates with La Quinta Formation. In the La Guajira peninsula, the formation is time-equivalent with the Rancho Grande Formation while to the south of its area in the Upper Magdalena Valley the Noreán Formation is correlated with the Saldaña Formation. The Lower Jurassic is missing in the Llanos Basin to the southeast of the extent of the Eastern Cordillera.
