k spatiotemporal variations in continental arc systems to explore the influence of tectonic outgassing of CO2 on these climatic shifts. These data indicate that global continental arc systems were spatially reduced at the onset of the Cryogenian glacial interval, widespread during the Cambrian greenhouse, and reduced during Ordovician cooling. The Cambrian greenhouse was coincident with ecologically stressed conditions, whereas Ordovician global cooling was accompanied by a major biodiversification event. Thus, variation in the continental arc CO2 flux likely played a critical role in major climatic fluctuations, which profoundly influenced early animal evolution.


In-situ Pb isotopic analysis of sulfides in abyssal peridotites: New insights into heterogeneity and evolution of the oceanic upper mantle
J. Blusztajn et al., Department of Geology and Geophysics, Woods Hole Oceanographic Institution, Woods Hole, Massachusetts 02543, USA; jblusztajn@whoi.edu. Published online ahead of print on 6 Jan. 2014, http://dx.doi.org/10.1130/G34966.1.

Abyssal peridotites and mid-ocean ridge basalts (MORBs) represent complementary residue-liquid products of melting and melt migration in the oceanic mantle. Because MORBs are mixtures of melts coming from different mantle depths, their isotopic signature do not directly describe the isotopic composition of the mantle source, but instead describes the average composition of different parts of the mantle. In contrast, abyssal peridotites, the residues of fractional melting and melt-rock reaction, should shed more light on distribution of isotopic heterogeneities. In-situ analysis of lead isotopes in sulfide grains from abyssal peridotites reveal that they preserve a record of mantle compositions not seen in whole rock basalts from the same area. The results presented here by J. Blusztajn and c
