Figure F34. Close-up photographs of centimeter-size crystals observed in vesicles, vugs, and voids in hand specimen basaltic samples. Core surfaces were photographed dry. Arrows point toward top of core. A, B. Voids (in moderately olivine-phyric basalt breccia) showing well-crystallized carbonates and zeolites: (A) intervals 330-U1374A-11R-2, 75–81 cm, and (B) 11R-2, 127–142 cm. C. Voids (in moderately olivine-phyric basalt breccia) showing well-crystallized globular carbonates and associated zeolites (interval 330-U1374A-11R-4, 73–81 cm). D, E. Coating of zeolite crystals in aphyric basalt breccia. Note the presence of well-formed crystals: (D) intervals 330-U1374A-68R-2, 100–106 cm, and (E) 68R-2, 110–113 cm. F. Radial crystal of zeolite filling a void (in aphyric basalt, intrusive sheet) (interval 330-U1374A-68R-5, 62–70 cm).
