Abstract
Bulk chemical analyses of andesites are used primarily in two ways to evaluate andesite origins. First, average elemental and isotopic compositions can be used to test genetic hypotheses and to compare volcanic rocks from different areas or ages (between-suite comparisons). Second, variation in the concentration of elements or ratio of isotopes within suites must also be consistent with the differentiation mechanisms proposed (within-suite variations).
