2865 meters above sea level. The volcanoes are distributed in a string-like pattern clustered from North to South in the middle on the
Tengchong basin and are characterized by post-collisional high-Potassium (K) calc-alkaline series eruptions. The TVF provides unique geographical and geological knowledge as understanding the geological processes of creation provides insight into aspects such as the history of volcanism during the Quaternary Era in the region and as well as compositional information of its source and crustal assimilants. The TVF can be visited in the Tengchong Volcanic Geothermal National Geological Park.`
428:. These emissions have a measurable role in global climate change because of two main counter-acting reasons. The uplift of the TVF sequesters carbon because soil production is faster atop mountain ranges where soil removes carbon dioxide from the atmosphere by trapping atmospheric carbon dioxide in limestone. However, in contrast, syn-collisional volcanism, post-collisional volcanism, subduction zone metamorphism and present-day hydrothermal activity in the TVF results in augmented levels of global carbon by releasing it as atmospheric carbon dioxide.
