Exempel på garnet

• These features suggest generation of the lamprophyre by partial melting of a metasomatized, garnet peridotite mantle source.

• The garnet neoblasts are also arranged in strings that define the foliation and lineation along with titanite.

• In weakly deformed gneiss, the mafic minerals (biotite, augite and hornblende) occur as irregular clusters, locally separated from plagioclase by coronas of garnet.

• Here, the igneous and corona textures are obliterated by the growth of amphibolite-facies assemblages with hornblende, plagioclase, biotite, garnet and zoisite.

• A method for calculating effective bulk composition modification due to crystal fractionation in garnet-bearing schist: implications for isopleth thermobarometry.

• The finegrained matrix is composed of plagioclase, quartz, garnet, biotite and hornblende and/or augite.

• The lower part of the metamorphic sole is composed of kyanite and garnet-bearing mica schist, mica schist, quartzite and marble.

• Melting is tentatively deduced to have commenced at + 100 km, straddling the garnet-spinel transition.

• All other phases use similar activity models except for white mica and garnet.
