As a result of a study by a subcommittee of the Geological Sciences Division of the National Academy of Sciences/National Research Council, an Intersocietal Committee on Instrumentation in Geochemistry and Mineralogy was formed in 1983. The three societies involved are the Geochemical Society, the Volcanology, Geochemistry, and Petrology Section of the American Geophysical Union, and the Mineralogical Society of America. As a contribution to this committee, the U.S. Geological Survey conducted a working group in January 1984 to develop a strategy for adoption of accelerator mass spectrometry by the earth sciences. The report of this working group (B. R. Doe et al., A strategy for adoption of accelerator mass spectrometry by the earth sciences, U.S. Geol. Surv. Open File Rep. 84-664, 38 pp., 1984) has now been published. The conclusions are as follows.
