Hydrogen Peroxide Treatment of Natural Lake Sediment Prior to Carbon and Oxygen Stable Isotope Analysis of Calcium Carbonate

Abstract The carbon and oxygen stable isotope ratios (δ13C and δ18O) of authigenic and biogenic lacustrine carbonates are commonly used as past climate proxies, and these carbonates are often preserved within organic‐rich bulk sediment. We measured the δ13C and δ18O of carbon dioxide evolved from fi...
