Figure F105. A. Oxide-bearing shear zone in mostly undeformed gabbro (Sample 305-U1309D-271R-1, 68–70 cm) (plane-polarized light; field of view [FOV] = 2 cm). B. Strongly localized oxide-rich band, deposited in an undeformed gabbro (Sample 305-U1309D-272R-3, 10–13 cm) (plane-polarized light; FOV = 2 cm). Oxide enrichment appears not to affect silicate modes.
