The volcanic field is located in China but geographically more closely related to Southeast Asia's volcano zones. It is located along the southeastern margin of the Tibetan Plateau near the Burma border. The uplift of the Tibetan Plateau occurred during the Cenozoic due to the Indo-Asian continent-continent collision. The Tengchong volcanic field is near the intersection of several faults and thrusts. It is bordered by two north-south trending strike-slip faults: the Jinsha-Red River Fault on the east and the Sagaing Fault on the west and two east-west trending strike-slip faults in the south area of field. The volcanic field consists of, in addition to the three largest volcanoes, between 65 and 97 other smaller volcanoes, all of which are pyroclastic cones. Around 25 of these still bear recognizable craters and cones.[2][3] All of the volcanoes are thought to be dormant or extinct and formed during the Quaternary period; the three largest are from the Holocene. In addition, several geothermal fields are scattered across Tengchong county and are deemed to be part of the volcanic field; they are also part of the Tengchong Volcanic Geothermal National Geological Park.[2]
