Fig. 3From: Serpentinite dehydration at low pressuresa Zone I&II Antigorite-olivine-tremolite-serpentinite schist (Sample Ol21) (Swiss army knife 9 × 2.5 cm). b Plain polarised light image of antigorite-olivine-tremolite-serpentinite-schist containing large patches of antigorite, small sub-idioblastic olivine, acicular tremolite and minor sub-idioblastic magnetite. Olivine and antigorite form a mosaic texture. c Crossed polarised light image of b. Antigorite shows a preferred orientation with tremolite growing oblique to the foliation. d Backscatter image of acicular tremolite, sub-idioblastic olivine and dark antigorite. e Backscatter image of a large relic Cr-magnetite showing inclusion-rich darker cores and recrystallized magnetite-rich rims. Magnetite also occurs as groundmass grainsBack to article page
