Huambo volcanic field is a volcanic field in Peru. Andahua-Orcopampa lies north-northeast and Sabancaya east of Huambo, [1] east of the Rio Colca. [2] The town of Huambo lies between the two fields. [3]
The northern part of the field was active 700 BCE ± 50 years, forming a large lava flow field and a cinder cone Cerro Keyocc. The southern part of the field contains other cinder cones and lava flows. Some may be of Holocene age. [1] Lava flows are a few 10 metres (33 ft) thick. Four among the volcanoes of the southern field are Marbas Grande, Marbas, Marbas Chico I and Marbas Chico II. [2] The formation of these fields may have been influenced by magma ascent along deep fault systems. [4]
Trachyandesite is the major eruption product of Huambo. [1] The magmas forming this field formed in deep magma chambers with little modification in shallower magma chambers. [2] Basement lava flows have been dated at 1.05±0.04 mya. [3] The Huambo field is located within the Arequipa crustal domain. [4]
