  • Oxidation of manganese in an ancient aquifer, Kimberley formation, Gale crater, Mars
  • 2016
  • In: Geophysical Research Letters. - 0094-8276 .- 1944-8007. ; 43:14, s. 7398-7407
  • Journal article (peer-reviewed)abstract
    • The Curiosity rover observed high Mn abundances (>25wt % MnO) in fracture-filling materials that crosscut sandstones in the Kimberley region of Gale crater, Mars. The correlation between Mn and trace metal abundances plus the lack of correlation between Mn and elements such as S, Cl, and C, reveals that these deposits are Mn oxides rather than evaporites or other salts. On Earth, environments that concentrate Mn and deposit Mn minerals require water and highly oxidizing conditions; hence, these findings suggest that similar processes occurred on Mars. Based on the strong association between Mn-oxide deposition and evolving atmospheric dioxygen levels on Earth, the presence of these Mn phases on Mars suggests that there was more abundant molecular oxygen within the atmosphere and some groundwaters of ancient Mars than in the present day

  • Elemental Constituents of Miami Aerosol as Function of Particle Size
  • 1976
  • In: Environmental Science & Technology. - : American Chemical Society (ACS). - 1520-5851 .- 0013-936X. ; 10:2, s. 176-182
  • Journal article (peer-reviewed)abstract
    • Results are presented of proton-induced x-ray emission analysis of aerosol samples taken in Miami, Fla., in the summer of 1974. Elemental concentrations and elemental ratios as a function of particle size are shown for 13 elements. These size distributions allow the determination of the sources of several elements observed in the Miami aerosol. Data from north Florida and Bermuda are compared.
