BackgroundVolcanism of the Tengchong volcanic field is related to the eastward subduction of the Burma microplate under the Eurasian plate near the northeastern side of the collision zone between the Indian and Eurasian plate, which forms the seismically very active Himalayan belt.
The Tengchong volcanic field formed in several periods from the early Pliocene to the Holocene.
1 Pliocene to mid-Pleistocene eruptions produced basaltic lavas.
2 Mid- to late-Pleistocene erupted silicic pyroclastic lavas
3 Holocene: basaltic to andesites. The youngest eruptions were in 2 phases during the early and late Holocene.
