Notes: Fo = forsterite, An = anorthite, Or = orthoclase, Cpx = clinopyroxene, Opx = orthopyroxene, Opaq = opaques, Hb = hornblende, Plag = plagioclase, Ol = olivine, Am = amphibole, Qtz = quartz. CP = crystal-plastic or brittle deformation intensity, Pt = point number, Gr = grain number prefixed by mineral abbreviation. Loc = location in grain: PtC = point in core, neo = neoblast, B = random point in grain interior. Sd = standard deviation (1 ). Only a portion of this table appears here.
