Figure F136. Modal and textural planar layering. A. Flattened varioles with shape-preferred orientation of plagioclase laths (Thin Section 1; Sample 309-1256D-75R-1 [Piece 8, 46–52 cm]) (field of view [FOV] = 10 mm; plane-polarized light, blue filter). B. Flattened and coalesced spherulites alternate with plagioclase-rich layers (Thin Section 10; Sample 309-1256D-80R-1 [Piece 10, 55–58 cm]) (FOV = 10 mm; plane-polarized light, blue filter).
