Figure F125. A. Corona texture in olivine gabbro consisting of talc, tremolite, and 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; magnification = 10×). B. Corona texture with pseudomorphic talc/tremolite/serpentine with accompanying late calcite in the core of the pseudomorph (Sample 305-U1309D-115R-2, 89–91 cm) (cross-polarized light; magnification = 1×).
