    Abstract. Materials containing Fe 2+ are, in principle, metastable under the oxidizing conditions that exist in the ambient environment. The higher overall Fe 2+ /Fe 3+ ratio of sediments relative to that of the total crust (1.53 vs. 0.53, cf. Chapter 8) bears witness to the oxidation of Fe 2+ when minerals containing this cation become exposed to environmental conditions.

    2016-11-19 · The space of metastable materials offers promising new design opportunities for next-generation technological materials, such as complex oxides, semiconductors, pharmaceuticals, steels, and beyond. Although metastable phases are ubiquitous in both nature and technology, only a heuristic understanding of their underlying thermodynamics exists.

  • The Effect Of Metastable Pyroxene On The Slab

    The persistence of metastable pyroxene has a much stronger effect (Figures 1b and 1c). Inside the PX1 and PX2 slabs, metastable pyroxene extends down to 670 km depth, before transforming into its higher-pressure polymorph. By contrast, olivine metastability is limited to the cold inner core of the slab with temperatures below 650°C (Figure 1b).
