Inselbergs Near Medellín

Abstract

The northernmost part of the Central Cordillera is characterized by plateaus stretching from 1900 to 2700 m a.s.l. which were formed by erosion before the uplift of the cordillera, their different altitudes is an evidence of the successive pulses which were separated by quiet periods. One of the results of these tranquil epochs was the appearance of bornhardts at different altitude. Carved during Miocene and Pliocene in the Antioquian Batholith, a granodiorite intrusive which crystallized in the Upper Cretaceous. Main inselbergs are the Peñol de Guatapé (1900 m s.a.l.) the Tabor Mount (1880 m a.s.l.) in San Carlos and the Peñol de Entrerrios (2300 m a.s.l.).
