Figure F20. A. Troctolite layer showing well-developed corona mesh texture (interval 304-U1309B-15R-2, 53–64 cm). Lighter green areas are actinolite after relict clinopyroxene. Original grain boundaries are outlined by dark green (appears black) chlorite. B. Corona texture in olivine gabbro consisting of talc, tremolite, oxides after olivine, and chlorite after plagioclase where the two original minerals were in contact (Sample 305-U1309D-80R-2, 16–19 cm) (cross-polarized light; field of view = 1.4 mm).
