maficDuring this stage, themaficminerals grow faster than plagioclase, exhausting the local melt inmaficcomponents.From theCambridge English CorpusSmall amounts ofmaficand opaque minerals occur.From theCambridge English CorpusOn the basis of our combined data, a more appealing model for themafic-ultramafic complexes is the emplacement of solitary intrusions.From theCambridge English CorpusThis is in agreement with return to moremaficdetritus and the proposed increased upper continental crust contribution, together at the expense of felsic detritus.From theCambridge English CorpusIn continental rift settings, the emplacement of such large volumes of felsic melts requires a huge amount ofmaficmagma derived from uprising asthenosphere.From theCambridge English CorpusIn particular, the heat for the melting may have been supplied bymaficmantle-derived magmas.From theCambridge English CorpusIn weakly deformed gneiss, themaficminerals (biotite, augite and hornblende) occur as irregular clusters, locally separated from plagioclase by coronas of garnet.From theCambridge English CorpusThemaficmagmas were probably derived from the upper mantle (spinel stability field) by 9 % partial melting.From theCambridge English CorpusSampling was limited to the chromitite layers and laminae that occur in themafic-ultramafic cumulates of these complexes.From theCambridge English CorpusThe thrust truncates a number of verticalmaficlayers in the footwall block.From theCambridge English CorpusIt is obvious that the compositions ofmafic- ultramafic complexes like these have been greatly influenced by cumulate processes.From theCambridge English CorpusIn general, eclogites are predominantlymaficand are preserved as boudins within felsic gneisses.From theCambridge English CorpusThe formation is vertically zoned with the appearance of banded andmaficpumices approximately 8 cm above the base of the ignimbrite.From theCambridge English CorpusThemaficshells do not show up clearly due to weathering.From theCambridge English CorpusAmphiboles from the core, the inner and outermaficshells and the matrix were analysed.From theCambridge English CorpusThese examples are from corpora and from sources on the web.
