Figure F73. Photomicrographs showing a variety of variolitic textures. A. Very fine varioles consisting of curled plumose clinopyroxene intervened with thin plagioclase laths (Sample 206-1256D-57R-4, 77-78 cm; width of view = 0.7 mm). B. Fine varioles consisting of sheaflike clinopyroxene (Sample 206-1256C-6R-5, 76-80 cm; width of view = 2.7 mm). C. Medium varioles with platy plagioclase more developed than granular-prismatic clinopyroxene (Sample 206-1256D-53R-3, 24-25 cm; width of view = 0.7 mm). D. Coarse varioles consisting of stubby-platy plagioclase enclosing radially arranged clinopyroxene (Sample 206-1256D-3R-3, 85-89 cm; width of view = 2.7 mm).
