Other parameters, such as light, nutrient levels, and growth rate, may also affect Mg substitution in biogenic calcite [Delaney et al., 1985; Nu¨rnberg et al., 1996; Lea et al., 1999], but appear to be less important than temperature. Recent theoretical models suggest that low cell-specific sulfate reduction rates (csSRR) in marine sediments should result in high S-isotope fractionation factors (1). Etna – implications in the chemistry of chlorine and bromine species in volcanic plumes . started to accrete from the solar nebula (9).The heat produced by impacts during accretion was probably sufficient to cause large-scale, and possibly complete, melting of the planet (10).Molten metallic iron would have separated We analyzed temporal and spatial signatures of ocean storms on seismic records in the South China and East China Seas. The 15-km-wide Corbetti caldera overlaps the NW margin of the older 30 x 40 km Awasa caldera. Existing studies on marginal sediments show actual fractionation factors indeed approach the theoretical equilibrium fractionation of 70‰ (2,3,4). 1. Variations in sea level associated with climatic cycles, and in particular ice ages, may similarly impact the rate of melting and volcanism throughout the world's oceans [Lund and Asimow, 2011].

The pronounced negative conversion factor appears in the PSP region the depths 50 km and below 200 km, indicating that the density anomalies in the uppermost and lower layers in the upper mantle are likely dominated by compositional effects. 1 Author version: Geochem.Geophys.
