    However, olivine diogenites with olivine contents 25% are spectrally indistinguishable from olivine‐free diogenites (McSween et al. 2013), so the presence of olivine diogenite in the basin is entirely plausible. Furthermore, if olivine is present as dispersed, thin layers, then the resolution of Dawn's visible and infrared spectrometer (100s ...

    Apr 10, 2016 The olivine and plagioclase-bearing pyroxenite unit identified by corelogging is a marker horizon within the ultramafic intrusion (modelled in blue). Discrete layers are discontinuous making recognition of this sequence difficult and thereby complicating exploration for further mineralisation.

    Jan 01, 2000 The pyroxenite in Fig. 6 (analysis of a sample from the Granulitgebirge) will see only three out of the 13 invariant points in Fig. 3. The pyroxenite in Fig. 7 (analysis from an Erzgebirge sample) contains more MgO (+FeO) and less CaO than the rock in Fig. 6. This composition yields a markedly different topology, with eight stable invariant points.

    Feldspathic pyroxenite (FPYX) has a higher feldspar content than pyroxenite (PYX), resulting in a higher mean UCS. The curves in Figure 3 indicate an inverse relationship between grain size and rock strength for unaltered rocks. This relationship was confirmed with a set of 41 feldspathic pyroxenite samples from exploration core. The variability in

  • The Role Of The Antigorite  Brucite To Olivine Reaction

    The Role Of The Antigorite Brucite To Olivine Reaction

    Oct 26, 2020 Metamorphic olivine formed by the reaction of antigorite + brucite is widespread in serpentinites that crop out in glacier-polished outcrops at the Unterer Theodulglacier, Zermatt. Olivine overgrows a relic magnetite mesh texture formed during ocean floor serpentinization. Serpentinization is associated with rodingitisation of mafic dykes. Metamorphic olivine coexists with magnetite, shows ...

    Within the allochthonous Cabo Ortegal mafic-ultramafic complex of NW Spain abundant pyroxenite occurs in km size peridotite massifs of Limo, Herbeira and Uzal. In the Herbeira massif, pyroxenite forms a lens-shaped body ca. 3 km long and 300 m thick, essentially composed of websterite bands separated by minor dunite.

    Implications For The Seismic Detection Of Pyroxenite In

    When olivine transforms to wadsleyite at approximately 410 km depths, the situation changes in that pyrolite will become seismically faster by about 2.3(8)% in V p and 3.8(8)% in V s than pyroxenite. Similarly, the velocity contrast between eclogite/metabasalt and pyroxenite ranges from 1.3(13)% in S-wave velocities to 2.4(10)% in P-wave ...

    Dec 15, 2019 The olivine veinlets in clasts V1–V5 fill the fractures of pyroxene grains, and typically have sharp boundaries with their host pyroxene (Figs. 2 and 3). Most olivine veinlets observed in NWA 11273 are cut through by multiple fractures (e.g., Figs. 2c, 2e, 3b, and 3d). It should be noted that we did not observe the olivine veinlets occurring ...
