Evaluation of the effect of oven roasting at 340 gradC, bleach, 30% H2O2, and distilled/deionized water on the delta13C value of speleothem carbonate
Abstract:
Organic compounds derived from plants are found in many cave formations, which are collectively speleothem CaCO3 have distinct ratios of the stable isotopes of carbon (12C and 13C) that are expressed as ?13C values. Values of ?13C in the organic compounds are lower than ?13C values of speleothem calcium carbonate and could affect the ?13C values of speleothems with high organic conventionally used to destroy organic matter in carbonates prior to geochemical analysis were evaluated in this study. The treatments were oven roasting at 340 C, soaking in bleach, soaking in 30% H2O2, and soaking in distilled deionized water. There is no statistically significant difference between results from untreated and treated samples. These results suggest that the treatments do not affect the ?13C value of speleothems calcium carbonate. The treatments might be helpful in removing organic matter in speleothems that have high concentrations of organic matter. However, most speleothems have low organic carbon concentrations that do not affect the ?13C value of the speleothem, even if left untreated. Ultimately these treatments only need to be applied to speleothems with unusually high concentrations of organic matter.
