Four facts about this belt are analyzed in this work:(1)typical mantle metasomatism existing in the volcanic rocks and in their inclusions,(2)the distribution range of the K-rich volcanic belt estimated according to the K2O/Na2O ratio of the volcanic rocks,(3)the "cold spring and taele phenomenon" caused by adiabatic expansion of the mantle gases,and(4)the current situation of seismic activities.

This paper mainly deals with the elemental and isotope geochemistry of the Cenozoic potassic lava in this area, the petrology, mineral chem.
