N1 - Funding Information:
We thank Dr S. Fukutani (KURRI) and Prof T. Fujii (Osaka University) for their helpful suggestion and comments in discussion about bromine in manganese nodules. We are grateful to Dr. J. Bennett (Australian national nuclear research and development organization, ANSTO) for his English correction and valuable comments. The authors express their gratitude to the members of the research reactor group in KURRI for the preparation and operation in the neutron irradiation and to a programme for the cooperative use of KUR supported by Kyoto University. The USGS materials were supplied through joint research project between Shimizu Corporation and KURRI, and we would like to thank Dr N. Kinoshita (Shimizu Co.) for arrangement of those materials. Constructive comments from two anonymous reviewers and Editor M. Horan are gratefully acknowledged. This study was partly supported by a grant-in-aid from the Ministry of Education, Science and Culture (KAKENHI 25790081) in Japan for SS and by a grant-in-aid for scientific research by MEXT (to ME).

N2 - Trace amounts of three halogens (chlorine, bromine and iodine) in seventeen U.S. Geological Survey (USGS) geochemical reference materials were determined by radiochemical neutron activation analysis (RNAA). The materials analysed were AGV-2 (andesite), BCR-2, BHVO-2 and BIR-1a (basalts), CLB-1 (coal), COQ-1 (carbonatite), DGPM-1 (disseminated gold ore), DNC-1a (dolerite), DTS-2b (dunite), GSP-2 (granodiorite), Nod-A-1 and Nod-P-1 (manganese nodules), QLO-1a (quartz latite), SBC-1 (marine shale), SDC-1 (mica schist), SGR-1b (shale rock) and W-2a (diabase). The chlorine, bromine and iodine contents were determined to be 5.64 mg kg−1 (BIR-1a) to 4410 mg kg−1 (Nod-A-1), 0.039 mg kg−1 (BIR-1a) to 52.1 mg kg−1 (CLB-1), and 0.041 mg kg−1 (BIR-1a) to 599 mg kg−1 (CLB-1), respectively. The RNAA data of the three halogens were compared with the corresponding data in the literature.
