Figure F62. Downhole series of binary images from Gabbro 1 in Hole 1256D (pictures were taken on wet archive halves). Zone 1 is characterized by large and abundant leucocratic (plagioclase-rich) patches. Zone 2 is dominated by relatively small and few leucocratic patches, with the exception of Sample 335-1256D-217R-1A, 87–92 cm, which shows an anomalously high percentage of patches. Zone 3 is characterized by a higher abundance of patches than Zone 2 and an increasing abundance of patches toward the top of the zone.
