Huambo volcanic field
15°50′S 72°08′W / 15.83°S 72.13°W / -15.83; -72.13[1]
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]
