- d18O (LS09LACA): interpretation2_basis: ‘The oxygen isotope
composition of ostracod carapaces depends primarily on the d18O
composition of the water and the tempera- ture at which carbonates
precipitate (Craig, 1965; Stuiver, 1970). In tropical, closed-basin
lakes within seasonally dry climates, the d18O value of lake water is
controlled primarily by the evaporation to precipitation ratio (E/P) of
the lake (Fontes and Gonfiantini, 1967; Gasse et al., 1990). During
periods of increased (decreased) E/P ratios, the d18O value of lake
water will go up (down) as kinetic fractionation processes lead to an
increase (decrease) in concen- trations of 18O relative to 16O. Assuming
that long-term tempera- ture changes in the tropics are less likely to
affect d18O values in the lake than are changes in the E/P ratio (Covich
and Stuiver, 1974; Curtis and Hodell, 1993), the d18O value of ostracod
carapaces should indicate variations in the E/P ratio of the lake.’ has
