Figure F303. Grain-scale textures in dikes and gabbros. A. Intensely fractured plagioclase glomerocryst in otherwise unfractured basaltic grain-scale texture (Thin Section 6; Sample 312-1256D-174R-1, 130–134 cm) (plane-polarized light; field of view [FOV] = 2.25 mm). B. Slightly bent plagioclase lath in basalt (Thin Section 39; Sample 312-1256D-198R-1, 45–49 cm) (cross-polarized light; FOV = 0.562 mm). C. Fractures in a large plagioclase grain in gabbro filled with secondary minerals (Thin Section 69; Sample 312-1256D-214R-2, 15–17 cm) (cross-polarized light; FOV = 2.25 mm). D. Fractures in plagioclase filled with secondary minerals (Thin Section 71; Sample 312-1256D-215R-1, 84–88 cm) (cross-polarized light; FOV = 4.5 mm). E. Fractured plagioclase lath between amphibolitized pyroxene grains (Thin Section 63; Sample 312-1256D-214R-2, 0–6 cm) (cross-polarized light; FOV = 4.5 mm). F. Microcataclasite along grain boundaries of plagioclase with no evidence of shear strain (Thin Section 62; Sample 312-1256D-214R-1, 121–124 cm) (plane-polarized light; FOV = 2.25 mm).
