Figure F16. Photomicrograph, with crossed polars, of Sample 187-1162A-2R-1, 1-3 cm (see "Site 1162 Thin Sections"), showing the spherulitic zone in metabasalt from Hole 1162 (Unit 1) in which spherulites and mesostasis have been replaced by actinolite. Note the curved vein of recrystallized quartz that shows strain extinction and preferred orientation of crystallographic axes.
