Figure F10. Photomicrographs of examples of skeletal titanomagnetite developed in coarser grained rocks of Hole 1213B. A. Equant skeletal grains, possibly cross-sections of longer chains (Thin Section 42; Sample 324(198)-1213B-28R-1, 45–48 cm). B, C. Titanomagnetite intergrown with plagioclase (Thin Section 45; Sample 324(198)-1213B-32R-4, 39–41 cm). D. Long curving titanomagnetite chain spanning the width of an intersertal space (Thin Section 43; Sample 324(198)-1213B-28R-3, 143–145 cm). E. Titanomagnetite chain spanning the shorter distance across an intersertal space, rooted in clinopyroxene (light gray reflectivity compared with darker gray for plagioclase) (Thin Section 48; Sample 324(198)-1213B-31R-3, 73–75 cm). Cross-polarized light.
