Abstract:For mineral composition, chemical composition, rare earth elements of basalt, etc, the characteristics of petrology and geochemistry of alkali-olivine basalt, olivine basalt and trachy basalt in Lancang volcanic belt was expouded in detail, and the basalt in the belt which belongs to alkali basalt of potassic series was pointed out. On the basis of above-mentioned study, the tectonic setting, in which the basalt occurred, had been discussed.
