  • Oxygen isotope ratios from tree rings containing compression wood
  • During studies of oxygen isotope : temperature relationships for tree rings in the Canadian Rockies, the AA. noted differences in oxygen isotope ratios between samples from compression wood and normal radii in the same stem. This paper briefly
  • 1990
  • Strontium isotopes in trees as an indicator for calcium availability
  • Preliminary analyses of water (precipitation, throughfall, runoff, soil-water), soil (mineral matter) and biological material (trees, musselshells) show that the use of the strontium isotope ratio 87 Sr/86Sr is a powerful tool in estimating

  • The amino acid correlations with U-series coral dates in South Carolina, Bermuda, and the Mediterranean argue that the classical Canepatch and its Horry Clay date from isotope stage 5. The Canepatch shows the double marine transgression visible
  • 1990
  • By using the sedimentary facies, sedimentary structures, authigenic minerals, and stable isotopic compositions of oxygen and carbon in the calcite cements, the AA. interpret the tectonic-autocyclic processes and climatic variations that generated
