     "abstract": "Uranium-series disequilibria in whole-rock samples and \nmineral separates provide unique insights into the time scales \nand processes of magma mixing, storage, and crystallization. \nWe present 238U-\n230Th-226Ra data for whole-rock dacite and \ngouge samples and for plagioclase separated from two dacite \nsamples, all erupted from Mount St. Helens between October \n2004 and April 2005. We also present new 238U-230Th disequilibria for a suite of four reference samples from the 1980-86 \neruption of Mount St. Helens. We use the U-series data to \nevaluate the origin of the 2004-5 magma, its relation to the \n1980-86 magma, and the relation of 2004-5 phenocrysts to \ntheir host magmas. Dacite samples from 2004-5 show variable \n(\n230Th)/(238U), ranging from 238U-enriched to 230Th-enriched. \n(\n230Th)/(232Th) ratios in 2004-5 dacite and gouge samples do \nnot vary outside of analytical error and are within the range of \n(\n230Th)/(232Th) measured for the 1980s reference suite. However, (230Th)/(232Th) for plagioclase separates for dome samples \nerupted during October and November 2004 are significantly \ndifferent from corresponding whole-rock values, which suggests that a large fraction (>30 percent) of crystals in each \nsample are foreign to the host liquid. Furthermore, plagioclase \nin the two 2004 samples have U-series characteristics distinct \nfrom each other and from plagioclase in dacite erupted in \n1982, indicating that (1) the current eruption must include a \ncomponent of crystals (and potentially associated magma) \nthat were not sampled by the 1980-86 eruption, and (2) dacite \nmagmas erupted only a month apart in 2004 contain different \npopulations of crystals, indicating that this foreign component \nis highly heterogeneous within the 2004-5 magma reservoir.",
