Both deep seismic sounding (DSS) and magnetotelluric sounding (MT) data suggest that there exist still magma chambers within crust in Tengchong volcanic field (TVF) present-day, but there are differences on their number and spatial distribution and their complete picture still lack good understanding. There are 3 magma chambers within crust in TVF. The 1st one locates beneath Tengchong County-Rehai area, the 2nd one locates beneath Mazhan-Qushi area, and the 3rd one locates beneath Wuhe-Longjiang-Tuantian-Puchuan-Xinhua area. These 3 magma chambers constantly being fed with mantle melt materials, among which, it is the most obvious for the 1st one to be fed continuously with mantle melt materials.
