  • In extreme pH environments where [CO3 2-] is dominant (pH > 9.5), shifts in chemical and isotopic equilibrium of the H2O-DIC-CaCO3 system cause carbonates to follow a different equilibrium TΔi relationship.

    “This means that in extreme pH environments (such as where [CO 3 2-] is dominant, pH > 9.5), shifts in the chemical and isotopic equilibrium of the H 2 O-DIC-CaCO 3 system cause carbonates to follow a different equilibrium Ti relationship (Tripati et al. 2015, Watkins & Hunt 2015).”

    From Frontiers of Carbonate Clumped Isotope Thermometry (2023) · cites this paper as Tripati et al. 2015

    Section 3.2 says pH changes the equilibrium isotopic composition of the DIC pool, and the Abstract says rapidly growing carbonates may record a DIC species’ signature. But section 3.2 explicitly says equilibrium mineral compositions depend on temperature, not pH. The claim omits the rapid-growth qualification and incorrectly presents the resulting carbonate signature as a different mineral equilibrium temperature relationship; section 2.2.1 also places roughly equal bicarbonate and carbonate concentrations at pH 10.2, rather than carbonate dominance throughout pH > 9.5. (LLM, conf=0.86)

  • Equilibrium clumped isotopic compositions of DIC species depend on temperature, but at a given temperature fewer clumped isotopologues are found in CO3 2- than in HCO3- or H2CO3.

    “Equilibrium clumped isotopic compositions of the DIC species depend on temperature, but at a given temperature fewer clumped isotopologues are found in CO 3 2-than in HCO 3 -or H 2 CO 3 (Hill et al. 2014, Tripati et al. 2015).”

    From Frontiers of Carbonate Clumped Isotope Thermometry (2023) · cites this paper as Tripati et al. 2015

    Section 3.1.3.1 says equilibrium clumped-isotope compositions of DIC species vary with temperature, and the Fig. 4 description reports that CO3²⁻ has a lower value than HCO3⁻ at a given temperature. The passages in our copy do not establish the comparison with H2CO3, so that part of the sentence is not supported by this source. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Mineral precipitation occurring over a period of months removes the possibility of any pH-related disequilibrium effect being recorded in carbonate clumped isotope values.

    “Mineral precipitation occurring over a period of months removes the possibility of any pH-related disequilibrium effect being recorded in carbonate clumped isotope values (Hill et al., 2014;Kluge et al., 2018;Tripati et al., 2015).”

    From Reconstructing the temperature and origin of CO2 mineralisation in CarbFix calcite using clumped, carbon and oxygen isotopes (2024) · cites this paper as Tripati et al., 2015

    Section 4.3 says that carbonate minerals growing slowly enough to reach lattice equilibrium have clumped-isotope values independent of solution chemistry, including pH. But Section 4.2 says the growth-rate threshold depends on mineral-growth conditions; the paper does not establish that precipitation over months necessarily eliminates pH-related disequilibrium. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Deviations from the equilibrium ∆63 vs. ∆64 curve can suggest some kind of disequilibrium in the sample.

    “Deviations from this curve can suggest some kind of disequilibrium in the sample (see Tripati et al. 2015 for further discussion).”

    From Theoretical constraints on the effects of added cations on clumped, oxygen, and carbon isotope signatures of dissolved inorganic carbon species and minerals (2020) · cites this paper as Tripati et al. 2015

    Section 1.1 says disequilibrium Δ63 values may be recorded by carbonate minerals, and the equilibrium-prediction tables list both Δ63 and Δ64 values. However, our copy does not discuss deviations from a Δ63-versus-Δ64 equilibrium curve as a diagnostic of disequilibrium. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • Paired measurements of ∆63 and ∆64 can provide constraints on which processes shape observed isotopic signatures in experimental samples.

    “Paired measurements of ∆ 63 and ∆ 64 can provide constraints on which processes shape observed isotopic signatures in experimental samples, as described initially in Tripati et al. (2015).”

    From Theoretical constraints on the effects of added cations on clumped, oxygen, and carbon isotope signatures of dissolved inorganic carbon species and minerals (2020) · cites this paper as Tripati et al. (2015)

    Section 4.3.2 proposes that coupled clumped-isotope measurements may help identify disequilibrium processes, supporting the general idea. But it specifies Δ47, Δ48, and Δ49 in field-collected carbonate minerals, not paired Δ63 and Δ64 measurements in experimental samples. Section 2.1 defines Δ63 and Δ64 but does not propose that pairing. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
