abstract

  • Oxidation variation between the cooling faces of a single lava has been studied by polished section examination, and Fe2O3: FeO chemical analysis. The oxidation state, which is at a maximum toward the center of the lava, developed during the initial cooling, and has very marked magnetic expression. The Th: U ratio varies in harmony with the oxidation state emphasizing the problem of "resentative" sampling of the body. Examination of thirteen additional bodies suggests that in lavas there exists at least a partial dependence of the oxidation variation development on the lava thickness or interior cooling rate. © 1967 Springer-Verlag.
