Figure F15. Basaltic intervals recovered from ghost cores (photomicrographs under crossed polars). A. Aphyric basalt (Thin Section 25; Sample 345-U1415J-2G-1, 0–4 cm [Piece 1]; Interval G1). B. Dolerite (Thin Section 26; Sample 345-U1415J-2G-1, 4–8 cm [Piece 1]; Interval G2). C. Aphyric basalt with euhedral olivine phenocrysts (Sample 345-U1415J-17G-1, 8–12 cm [Piece 2]; Interval G56). D.
