Figure F169 (continued). E. Magmatic vein crosscutting pegmatitic gabbro (interval 305-U1309D-165R-1, 87–107 cm). Yellow box = location of F and G. F. Boundaries of the magmatic vein surrounded by the pegmatitic gabbro (Sample 305-U1309D-165R-1, 90–93 cm) (plane-polarized light; FOV = 2 cm. G. Same as F; cross-polarized light. Yellow box = location of H. H. Interaction of the magmatic vein boundary with the pegmatitic gabbro (cross-polarized light; FOV = 11 mm). Center of the vein is made up of amphibole crystals.
