Figure F55. Subtrachytic plagioclase groundmass crystal alignment around glomerophyric olivine pseudomorphs in Sample 192-1183A-68R-1 (Piece 3A, 32-35 cm), Unit 8. This sample is from the area depicted in Figure F41, , that illustrates a pillow inflation texture. The groundmass grain size variations shown here are consistent with this interpretation (field of view = 2.8 mm; crossed polars; photomicrograph ID# 1183A
