Aggregates are composed of several coalescing mica flakes extracted directly from the rock by gentle crushing (i.e., as small chips, <100 µg), with their internal textural association preserved. These are single-phase, small-sized populations containing a range of mica crystals in terms of size and, possibly, specific 40 Ar/ 39 Ar composition ...

The crust‐mantle interaction in continental subduction channels: Zircon ...
1 Introduction. Subduction zones are the major sites for mass and energy exchange between crust and mantle, and thus subduction zone processes are a key to the heterogeneity of the mantle and the chemical differentiation of Earth [e.g., Stern, 2002; Zheng and Hermann, 2014].Orogenic peridotites (peridotite massifs or Alpine-type peridotites) are volumetrically minor in the continental crust ...

DC67 is a harzburgite containing abundant medium to coarse-grained olivine and orthopyroxene, with minor clinopyroxene ( Fig. 2 b) and altered, Ca-rich plagioclase, with accessory amphibole and magnetite. Both pyroxenes in this sample contain exsolution lamellae, consistent with crystallisation at high temperatures (i.e. igneous settings).

In contrast, Ni isotopes were significantly fractionated by pure cultures of methanogens. The largest fractionation, #60Ni of -1.46 ± 0.08‰, was achieved by a methanogenic hyperthermophile. Our data suggest the biological cycling of Ni may be an important contributor of Ni isotopic variations in the rock record.
