Photomicrographs showing textures and mineral assemblages of metagabbro (a, b), olivine gabbro (c, d), and serpentinites (e, f); (a) coarse deformed grains of plagioclase (Pl) crystals altered to cloudy kaolinite, surrounded by clinopyroxene (Cpx) and hornblende. (b) clinopyroxene (Cpx) altered to hornblende (Hbl), tremolite (Trm), chlorite (Chl). (c) olivine (Ol) crystals hosted in coarse plagioclase (Pl). (d) plagioclase (Pl) altered to saussurite associated with clinopyroxene (Cpx) altered to hornblende (Hbl) and chlorite with little opaques. (e) mesh texture of antigorite (Atg), (f) patches of magnetite (Mt) crystals hosted in antigorite (Atg). Abbreviations: Pl plagioclase, Cpx clinopyroxene, Hbl hornblende, Chl chlorite, Trm tremolite, Act Actinolite, Opq opaque minerals, Ol Olivine, Mgs magnesite, Atg antigorite, Mt magnetite.
