A 133Cs+ primary ion beam with an intensity of ~1.6 nA was focused to a diameter of ~10 µm. For smaller domains, a 133Cs+ primary ion beam with an intensity of ~30 pA was focused to a diameter of ~3 µm. Charging of the sample surface was compensated by Au-coating and an electron flood gun. Grains of UWC-3 calcite standard (d18O = 12.49 per mill V-SMOW, Kozdon et al. 2009) were cast in the center of each epoxy mount. Four to five consecutive measurements of UWC-3 calcite standard were performed before and after every set of up to 15 sample analyses. SIMS analyses for minor and major element concentrations were performed using a primary O- ion beam, with an intensity of 1 nA, focused to a ~ 1.5 µm beam spot size. Further, Mg/Ca measurements in small domains were performed on the CAMECA SX51 electron microprobe at the UW-Madison Department of Geoscience. ABSTRACT SUPPLIED BY ORIGINATOR: We report d18O and minor element (Mg/Ca, Sr/Ca) data acquired by high-resolution,in situ secondary ion mass spectrometry (SIMS) from planktic foraminiferal shells and 100–500 µm sized diagenetic crystallites recovered from a deep-sea record (ODP Site 865) of the Paleocene-Eocene thermal maximum (PETM). The d18O of crystallites (~1.2‰ Pee Dee Belemnite (PDB)) is ~4.8‰ higher than that of planktic foraminiferal calcite ( 3.6‰ PDB), while crystallite Mg/Ca and Sr/Ca ratios are slightly higher and substantially lower than in planktic foraminiferal calcite, respectively. The focused stratigraphic distribution of the crystallites signals an association with PETM conditions; hence, we attribute their formation to early diagenesis initially sourced by seafloor dissolution (burndown) ensued by reprecipitation at higher carbonate saturation. The Mg/Ca ratios of the crystallites are an order of magnitude lower than those predicted by inorganic precipitation experiments, whichmay reflect a degree of inheritance from“donor” phases of biogenic calcite that underwent solution in the sediment column. In addition, SIMS d18O and electron microprobe Mg/Ca analyses that were taken within a planktic foraminiferal shell yield parallel increases along traverses that coincide with muricae blades on the chamber wall. The parallel d18O and Mg/Ca increases indicate a diagenetic origin for the blades, but their d18O value ( 0.5‰ PDB) is lower than that of crystallites suggesting that these two phases of diagenetic carbonate formed at different times. Finally, we posit that elevated levels of early diagenesis acted in concert with sediment mixing and carbonate dissolution to attenuate the d18O decrease signaling PETM warming in “wholeshell” records published for Site 865.
