256: Geochemical analyses of glass separated from the Katmai-Novarupta 1912 and recent Augustine eruptions * *Sample numbers beginning with "Sk" are from Skilak Lake on the Kenai Peninsula; all other samples are from Augustine Island. Geochemical analyses of Katmai 1912 and recent Mt. Augustine Tephras Alaska. Details of EMP analytical procedures, including analyses of standards given in Beget et al. (1991). A;; Fe reported as Fe 3+. All analyses normalized to 100% to correct differential hydration. HSF=hydration scaling factor used to normalize each analysis. Prefix of SK=Skilak Lake sample numbers. ACT samples indicate tephras in permanent collection of the Alaska Center for Tephrachronology (ACT) at the University of Alaska. *
