Summary:Trace element abundances of andesite lavas from Jaishi volcano have been determined by XRF. Primitive mantle-normalized incompatible element pattern of these andesites is typical of calc-alkaline andesites, with distinct K, Ba and Rb enrichment and notable Ti depletion. In a Sr/(Ca-Ba/Ca diagram, these andesites do not give any Sr/Ca-Ba/Ca systematics, suggesting no effective fractional crystallization had taken place within the magma chamber during lava flow issuing activity.
