Figure F5. Sedimentary breccia from Section 336-U1383D-7X-CC. A. Section-Half Imaging Logger (SHIL) image of sediment breccia composed of poorly shorted angular clasts of palagonitized glass in light brown sedimentary matrix (clayey chalk) (interval 336-U1383D-7X-CC, 57–59 cm [Piece 10]). The breccias occur in contact with glassy pillow margins of sparsely vesicular aphyric basalt. B. Close-up photograph showing concentric and mottled alteration texture of palagonitized glass clasts and beige-colored micritic cement at the contact between the basalt and brecciated domain.
