Figure F112. Textures commonly found in Site U1309 gabbros and diabases. A. Brown hornblende (Hbl) in metagabbro (Sample 304-U1309B-9R-1, 38–41 cm) (plane-polarized light; field of view [FOV] = 2.4 mm). cpx = clinopyroxene. B. Cummingtonite (Cum) rimmed by actinolite (Act) in metagabbro (Sample 304-U1309B-10R-1, 111–113 cm) (cross-polarized light; FOV = 1.2 mm). C. Zeolite (Zeo) forming after plagioclase (Plag) in gabbro (Sample 304-U1309B-4R-1, 30–31 cm) (cross-polarized light; FOV = 1.2 mm). D. Textures of actinolite replacing (1) clinopyroxene and (2) olivine in diabase (Sample 304-U1309B-3R-1, 18–19 cm) (plane-polarized light; FOV = 2.4 mm). E. Pseudomorphs of chlorite (Chl) and tremolite (Trm) after olivine in troctolite, forming a corona structure (Sample 304-U1309B-15R-2, 84–85 cm) (plane-polarized light; FOV = 1.2 mm). F. Same as E; cross-polarized light.
