Figure F37. Close-up core photographs (arrows point toward top of core). A–C. Infillings of carbonates with a coating of reddish-brown minerals (goethite, Fe oxyhydroxides) in a sparsely olivine-phyric basalt breccia: (A) intervals 330-U1374A-37R-2, 62–68 cm, and (B, C) 37R-2, 65–68 cm. D. Carbonates and brown and black clay minerals in conjugate veins with centimeter-wide brown halo (interval 330-U1374A-7R-2, 80–94 cm). Core surfaces shown in A–C were photographed dry; core surface shown in D was photographed wet.
