Figure F42. Photomicrographs of deformation textures in a weakly deformed oxide gabbro intruding Hole 1274A peridotites (Sample 209-1274A-11R-1 [Piece 10, 46–49 cm]; ~57 mbsf). A. Bent plagioclase with deformation twins (cross-polarized light: blue filter; field of view = 2.75 mm; image 1274A_066). B. Recrystallized plagioclase with polygonal grain boundaries (cross-polarized light; field of view = 5.5 mm; image 1274A
