Bromine and iodine contents in geological samples can be used as useful tools to understand various environmental phenomena such as past sea-level changes, geological uplift and subsidence, as well as marine incursion to the inland due to paleo tsunami and storm surges. In this study, we measured bromine and iodine contents in possible standard materials and lake sediment samples using the WDXRF at Tono Geoscience Center and polarizing EDXRF at Tohoku University. We compared both results and confirmed that the WDXRF method for Bromine and iodine content determinations can provide the reliable results.
