Add a definition The primary mineralogy of the rock is completely replaced by albite, carbonate,sericite, epidote, clinozoisite and opaque minerals. From theCambridge English Corpus Other alteration products are chlorite,sericite, quartz and opaque minerals. From theCambridge English Corpus Some plagioclase crystals are altered tosericiteand clay minerals. From theCambridge English Corpus Alteration is variable: absent in many crystals, in others producing densesericiteaggregates which may show some recrystallization effects to produce coarser-grained white mica. From theCambridge English Corpus Feldspars, partially perthitic, are weakly altered to illite, kaolinite andsericite. From theCambridge English Corpus Plagioclase crystals are in the course of being replaced bysericiteand calcite. From theCambridge English Corpus Both pyroxene and plagioclase show alterations along their margins withsericiteand biotite as newly formed phases. From theCambridge English Corpus Most pyroxenes are pseudomorphed by amphibole or chlorite, and the feldspars are variably replaced bysericite, epidote and/or carbonate. From theCambridge English Corpus The two o dominating minerals are amphibole and plagioclase, with the latter strongly altered to saussurite andsericite. From theCambridge English Corpus Accessories are opaques, while chlorite, actinolite,sericiteand titanite are the secondary minerals. From theCambridge English Corpus These zones show the effects of intense alteration: the granite is transformed into a quartz-sericite-andalusite schist. From theCambridge English Corpus Other secondary minerals are albite,sericite, epidote and chlorite. From theCambridge English Corpus Some plagioclase crystals are replaced by albite andsericite; actinolite and chlorite develop in clinopyroxene pseudomorphs. From theCambridge English Corpus The deformation zone is also locally overprinted by cataclasites consisting of chlorite + quartz + calcite +sericite. From theCambridge English Corpus Veinlets and disseminations of quartz +sericite+ epidote + chlorite + pyrite + pyrrhotite + chalcopyrite are locally developed in the aureole.
