View table data :: Download table data (.csv)
* Major elements, Sr, Ba, V, Y, and Sc abundances analyzed by ICP at Indiana University, Fe2)3/FeO ratios determined by titration. Rb abundances analyzed by atomic absorption at Indiana University (M. Gilstrap, analyst). Hf, Th, and La abundances analyzed by INAA at Michigan State University. Error estimates (1s, relative percent) based on one set of five replicate analyses: Si (1.3), Ti (1.2), Al (1.3), Fe*(2.0), Mn(2.7), Ca (1.0), Na (4.4), K (3.0), Rb (2.6), Sr (1.3), Ba (1.8), Zr (2.2), V (0.8), Y (0.5), Sc (3.4), Hf (1.0), Th (1.0), La (1.0) *
