Major element analyses of whole rocks from Mt. St. Helens
Analyses of major elements (presented as weight percent oxide) in volcanic rocks from Mt. St. Helens, Washington, USA. The data table includes sample descriptions. More detailed sample descriptions are given in Blundy et al., (2008). Blundy, J., Cashman, K.V. and Berlo, K.

Data Quality
Samples were powdered using agate mills at the Open University. Major elements were determined on fused glass beads prepared using a lithium tetraborate flux (sample to flux ratio 1:5) and trace elements on 32 mm diameter pressed powder pellets prepared using a small quantity of Moviol 8–88 binding agent. Analyses were conducted on a PANalytical Axios Advanced XRF spectrometer at the University of Leicester. Loss-on-ignition (LOI) values were determined for all samples from powders dried overnight at 105 °C, then ignited at 950 °C for 1 h.
