Chemical composition of ocean-floor basalts and separated magnetites DSDP Legs 37, 45 and 46, supplement to: Schock, Hans Hartmut (1979): Distribution of rare-earth and other trace elements in magnetites. Chemical Geology, 26(1-2), 119-133

Hans Hartmut Schock
Titanomagnetites separated from 15 different rock samples (including ocean-floor basalts from DSDP Legs 37, 45 and 46) were analyzed together with whole-rock samples by instrumental neutron-activation analysis for Sc, Cr, Co, Zn, Hf, Ta, Th and the REE La, Ce, Nd, Sm, Eu, Gd, Tb, Dy, Tm, Yb and Lu. In titanomagnetities from ocean-floor basalts and some other rocks, REE are enriched with respect to the whole-rock composition by factors of between 1.5 and 3...
