    • 47 are on the order of ±0.01 to 0.02, leading to errors in temperature of ∼2° to 4°C. The key feature of this thermometer is that it is based on a homogeneous equilibrium within carbonate rather than on a heterogeneous equilibrium between carbonate and water or some other phase. Therefore, unlike conventional carbonate-water oxygen isotope thermometry, it does not require knowledge of the isotopic composition of water from which carbonate grew or of any other phase with which it might have undergone isotopic exchange.

    • SMOW value of -1.1. These results are consistent with reequilibration of this nodule during burial metamorphism at depths of ∼1 to 2 km and are inconsistent with any plausible conditions and water sources for original deposition. We suggest that the portion of this nodule sampled for analysis underwent a cryptic recrystallization event during burial metamorphism and after its original growth near Earth's surface.

    • m is the density of the mantle (assumed to equal 3.3 g/cc). See (15) for explanations of these choices of values for the physical constants. This relation predicts a maximum rate of elevation gain that is, not considering any elevation losses due to erosion) of 0.3 mm/year.
