Figure F167 (continued). E. Contact between gabbro and diabase (interval 305-U1309D-125R-2, 100–110 cm). Yellow box = location of F and G. F. Undulating boundary between gabbro and diabase (Sample 305-U1309D-125R-2, 104–106 cm) (plane-polarized light, FOV = 2 cm). G. Same as F; cross-polarized light. Yellow box = location of H. H. Undulating contact between gabbro and diabase (cross-polarized light; FOV = 11 mm). Microphenocrysts inside diabase show random texture.
