图2腾-景洪北西向新生破裂带地震构造图 Fig.

The tectonic stress field in Tengchong volcano areas is oriented as NNE-NE-NEE, nearing horizontal compr essive stress field.

腾火山构造应力场主要为北北东—北东—北东东向，接近压应力场。

It is inferred from the thermometry of geyserite and adarce inclusions that underground temperatures for the hot spring system in Tengchong are .

云南腾是中外著名地，内火山岩浆地活动强烈，显示形式多样，有温泉、泉、沸泉、蚀变岩石、泉华（硅华、盐华、钙华和硫华）等。
