Figure F9. Scanning electron microscopic backscattered electron images showing petrographic features of different rock types from Leg 187 samples. A. Fe-Ti oxide minerals (white contrast), clinopyroxene (light gray), and plagioclase (dark gray) in pillow basalt (Sample 187-1159A-2R-1, 26-30 cm [#57]). B. Titanomagnetite (tan contrast) and iron sulfides (extra bright) occur between thick plagioclase laths in massive basalt (Sample 187-1160B-9R-1, 111-116 cm [#67]). C. Titanomagnetite pseudomorphs showing well-oriented lamellae in metadiabase (Sample 187-1162A-5R-1, 33-37 cm [#74]). The areas surrounding the titanomagnetite pseudomorphs contain abundant secondary actinolite.
