It is the northernmost volcanic complex of the Andean Volcanic Belt with Fueguino in Tierra del Fuego, Chile, at the opposite end of the Andean mountain belt.The complex, comprising mainly felsic extrusive volcanic rocks as rhyolites, also is the only confirmed volcanic province in the Eastern Ranges, with traces of probably contemporaneous explosive volcanic activity in the vicinity of Guatavita, Cundinamarca.The Paipa-Iza volcanic field is important as a touristic site with thermal baths in both Paipa and Iza and is being studied for the potential of geothermal energy production and for the extraction of uranium in the area.

Etymology

The names Paipa and Iza originate in Muysccubun, the language of the indigenous Muisca, who inhabited the Altiplano Cundiboyacense before the Spanish conquest. Paipa was the name of a cacique who served under cacique Tundama of Duitama and Iza means “place of healing”.{{in lang|es}} Etymology Municipalities Boyacá

Paipa–Iza volcanic complex

(File:Paipa-Iza volcanic complex - Colombia - Rhyolite from Holcim dome.jpg|right|250px|thumb|Rhyolite from Holcim dome, Iza)The complex was active from the late Pliocene, around 2.7 Ma, until the earliest Pleistocene, around 2.3 Ma.Jaramillo et al., 2005Monsalve et al., 2011Romero & Rincón, 1990Vesga & Jaramillo, 2009The complex at Iza consists of two domes; Domo Holcim with {{convert|0.67|km2|sqft}} and Domo Los Sauces {{convert|0.12|km2|acre}} in size. They consist of porphyritic rhyolites with sanidine and plagioclase as dominant mineral groups and abundant xenoliths of sedimentary rock and in minor quantities volcanic or metamorphic fragments. The overall rock composition is very felsic and comprises biotites and amphiboles as opaque minerals.Monsalve et al., 2011, p.124

Geothermal energy

The complex is studied for the potential of geothermal energy production.Alfaro et al., 2010Mejía et al., 2014Moyano & Vallejo, 2015

Resources

The complex is studied for the potential of uranium mining.González Oviedo, 2009aGonzález Oviedo, 2009b
