The Batolito de Ibague is one of the major intrusive bodies which outcrops in the eastern part of the Colombian Central Cordillera. Metamorphic, sedimentary and volcanic rocks of Precambrian (?) to Jurasic (?) age were intruded by this Jurasic pluton. The batholith range from diorite to cuarzomonzonite with aplitic zones. Mineralogically, it presents irregular variations, especially in hornblende and biotite contents. The intrusion of the batholith took place, aparently, in an initial stage of a complex shear period within the Cordillera Central.
