Summary
Methods Total element abundances in the bulk tephra samples were determined by inductively coupled plasma mass spectrometry (ICP-MS) following a 4-acid digest at the USGS analytical laboratories in Denver, CO. Briefly, the tephra samples were digested using a mixture of hydrochloric, nitric, perchloric and hydrofluoric acids at low temperature following the methods of Crock and otheres (1983). The resultant fluid was aspirated into a 42-element ICP-MS for analysis following the analytical procedure of Briggs and Meier (2002). USGS geochemical reference materials BIR-1, BCR-1, and BHVO-1 were analyzed before and after Kilauea tephra samples for data quality control. Kīlauea sample A7-0641 was analyzed as an analytical duplicate; sample [...]

Kīlauea sample A7-0641 was analyzed as an analytical duplicate; sample 3-19 Clast was analyzed as both a digest duplicate and analytical duplicate.
