Figure F67. Trace element compositional variations for Site 1139 compared with Kerguelen Archipelago alkalic volcanic series which are divided as in Figure F66. The Unit 3 highly altered crystal-vitric tuff has (Nb/Zr)_N of 23.0 and (Zr/Y)_N of 1.5, but the data point does not show at the scale in the figure. Data from Weis et al. (1993) and Weis et al. (1998).
