Figure 5. SiO2 variation diagrams showing the major-element compositions (Al2O3, CaO, K2O, and FeO*) and subdivision into low-K and high-K series (after Sigurdsson and Loebner, 1981) of rhyolitic glass particles recovered at Sites 982 (open circles) and 985 (solid diamonds). All analyses were normalized to a volatile-free total of 100%.
