Total REE abundances and La/YB ratios in
these rocks vary from 98 ppm to 118 ppm and 7.1 to
9.1 respectively, with weak negative anomalies
evident in only three patterns. There is a slight
difference between patterns of the most salic andesite
and its groundmass (Nos. 9 and 8, Fig. 4); the
former shows weak positive Eu anomaly due to
accumulation of some plagioclase phenocrysts.
