Figure F116. Spidergrams showing compositions of altered material from Hole 1256D. A. hyaloclastite Sample 206-1256D-30R-1, 47-58 cm, normalized to constant Ti and compared to average composition of Unit 1256D-8. B. Brick-red hydrothermally altered basalt Sample 206-1256D-57R-3, 1-3 cm, normalized to constant Ti and compared to adjacent less altered basalt.
