Geochemical properties of the Beni Bousera (N. Morocco) peridotites : a field and laboratory approach to understanding melt infiltration and extraction in an orogenic peridotite massif
… peridotite groups suggest equilibration in the garnet stability field, and temperatures calculated from dysprosium concentrations are usually higher than those determined from two-pyroxene thermometry. Linear major element patterns versus MgO and whole rock REE compositions of Beni Bousera …

Studies on Chemical and Electrochemical Stability of Li-stuffed Garnets for Next Generation Lithium Batteries
… Among the solid Li-ion electrolytes, Li-stuffed garnets are deemed a very promising electrolyte due to their wide electrochemical window (> 6 V vs. Li/Li+), chemical stability against metallic Li, and high ionic conductivity (~ 1 mS cm-1) at room temperature. Even with these attributes, there is …

EVOLUTION OF THE EASTERN ALPS FROM THE PALEOZOIC ONWARD: CONSTRAINTS AND INSIGHTS FROM THE (ULTRA)BASIC ECLOGITIC COMPLEX OF MILCHENKAR ÖTZTAL-STUBAI COMPLEX (EASTERN ALPS, TYROL, AUSTRIA)
… the Central Metabasite Zone comprises abundant garnet amphibolites hosting variably retrogressed eclogites and subordinate occurrences of their gabbroic protoliths, often showing igneous cumulitic textures, with crystallization ages around 530 Ma (Miller & Thöni, 1995). In the Milchenkar area, …

Evaluating mantle and crustal processes using isotope geochemistry
… originated completely or partially in the garnet stability field. Mantle upwelling velocity for the Galapagos plume (Fernandina) ranges from ≈ 1 to 3 cm/y with a maximum porosity of 0.3%, indicating that Galapagos is a mildly buoyant plume. Very slow mantle upwelling rates and very low …

Textural and Chemical Relations Among Spinel-Sapphirine-Garnet-Orthopyroxene, Salt Hill Emery Mine, Cortlandt Complex, N.Y.
… spinel – sapphirine (Si/O=0.10), sapphirine – garnet (0.25), garnet – orthopyroxene (0.28), rather than directly from spinel to higher-silica minerals which would overstep intermediate reaction steps. However, observed reaction textures indicate the latter more complex behavior in which spinel …

The isotopic evolution of the British lithosphere
… melt extraction from the rocks while in the garnet stability field. The petrology and Sm-Nd isotope systematics of the plagioclase and pargasite peridotites record the local infiltration of a melt. Significantly the Sm-Nd isotope systematics of the "metasomatised" peridotites are the same as …

Trace element geochemistry of oceanic peridotites and silicate melt inclusions : implications for mantle melting and ocean ridge magmagenesis
… hotspots appear to have begun melting in the garnet stability field, deeper than samples recovered away from hotspots. Most samples show pronounced negative Zr and Ti anomalies, which increase with increasing incompatible element depletion (increased melting), on extended rare earth (spider) …
