Figure F77. Downhole variations of (A) plagioclase and (B) augite grain size in Unit 1256C-18. Solid circles = average maximum length, open circles = average maximum width, squares = diameter of a circle with an equivalent area to the crystal, crosses = maximum width/length ratio. C. Plagioclase grain size variation in Unit 1256D-1.
