Figure F50. Main vein types. A. Chlorite (Chl) vein with cross-fiber texture in clinopyroxene (Cpx) oikocryst-bearing troctolite (Thin Section 46; Sample 345-U1415J-8R-1, 34–37 cm [Piece 7]). B. Granular prehnite (Pr) vein with minimal reaction along the vein boundaries in olivine-bearing gabbro (Thin Section 48; Sample 345-U1415J-9R-1, 46–49 cm [Piece 7]). C, D. Zeolite (Zeo) vein cutting prehnite veins in olivine gabbro (Thin Section 54; Sample 345-U1415J-8R-3, 35–38 cm [Piece 6]). E, F. Zoned chlorite vein cored by carbonate (Car) that is cut by prehnite crystals that form radiating “bloom-like” structures in gabbro (Thin Section 34; Sample 345-U1415J-4R-1, 2–5 cm [Piece 1]). Pl = plagioclase. A, B, D, and F are under cross-polarized light; C and E are under plane-polarized light.
