Oxygen and hydrogen isotope evidence for a temperate climate 3.42 billion years ago

Hren, M. T., Tice, M. M., Chamberlain, C. P.·2009·Nature

Abstract

Stable oxygen isotope ratios (delta(18)O) of Precambrian cherts have been used to establish much of our understanding of the early climate history of Earth and suggest that ocean temperatures during the Archaean era ( approximately 3.5 billion years ago) were between 55 degrees C and 85 degrees C (ref. 2). But, because of uncertainty in the delta(18)O of the primitive ocean, there is considerable debate regarding this conclusion. Examination of modern and ancient cherts indicates that another approach, using a combined analysis of delta(18)O and hydrogen isotopes (deltaD) rather than delta(18)O alone, can provide a firmer constraint on formational temperatures without independent knowledge of the isotopic composition of ambient waters. Here we show that delta(18)O and deltaD sampled from 3.42-billion-year-old Buck Reef Chert rocks in South Africa are consistent with formation from waters at varied low temperatures. The most (18)O-enriched Buck Reef Chert rocks record the lowest diagenetic temperatures and were formed in equilibrium with waters below approximately 40 degrees C. Geochemical and sedimentary evidence suggests that the Buck Reef Chert was formed in shallow to deep marine conditions, so our results indicate that the Palaeoarchaean ocean was isotopically depleted relative to the modern ocean and far cooler (<or=40 degrees C) than previously thought.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Combined O and H isotope ratios have suggested surface temperatures <40°C.

    “Combined O and H isotope ratios have suggested surface temperatures <40°C (52), while O isotopes in Archean phosphates have produced 26° to 35°C upper limits (53).”

  • Early Earth's environment might have been more temperate than traditionally thought.

    “However, with a faint young sun, the surface of the early Earth may have been cold enough for significant ocean ice to form (Kienert et al. 2012;Feulner 2012), and the environment of the early Earth may have been more temperate than the traditional model suggests (Hren et al. 2009;Vincent et al. 2004).”
  • The early Earth could have provided a range of environmental niches stable for millions of years.

    “Recent work suggesting that the early Earth was more temperate (Valley et al. 2002;Hren et al. 2009), and the flux of impactors smaller and less damaging than previously thought (Boehnke and Harrison 2016;Abramov and Mojzsis 2009) predicts that, as a whole, the early Earth could have provided a range of environmental niches stable for millions of years.”

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.
