B-Be-Li Abundance and Isotope Data: Mt. Erebus-McMurdo VolcanicsEntry ID: Erebus_B-Be-Li
Abstract: A dataset of B, Be, and Li abundances, and Li and B isotopic ratios, for volcanic rocks from the McMurdo Volcanic Group, the Crary Mountains, and other intraplate volcanic centers, is available online at the University of South Florida. B, Be, and Li concentrations have been determined by DC Plasma spectrometry, following the methods of Ryan and Langmuir (1987;1988; 1993) and Ryan et al (1996). ... Li isotopic determinations follow the methods of Tomascak et al. (1999) and were conducted at the Department of Terrestrial Magnetism,.and B isotope determinations follow the methods of Tornarini and others (2002), and were conducted at the University of PIsa (Italy). Analytical precision for abundance and isotopic determinations are noted in the tabulation.
These data are the result of a completed NSF-OPP geochemical study of the McMurdo Volcanics, and an ongoing NSF-EAR study of the Li isotope systematics of intraplate volcanic rocks. The datasets will be augmented as current studies progress. These data are in part the product of mentored research efforts by USF undergraduate and graduate students from 2000-present.
