Figure F31. Plot of major and trace element data for dolerite and metadolerite samples from talus at Sites 1108, 1111, and 1114 normalized to the average values for unaltered dolerite from Site 1109. Key: 1 = foliated, epidote-rich schist in Hole 1111A (Sample 180-1111A-16R-CC, 8-15 cm); 2 = metadolerite pebble in sediments of Hole 1108B (Sample 180-1108B-47R-CC, 1-3 cm); 3 = nonfoliated metadolerite in Hole 1114A (Sample 180-1114A-36R-2, 40-42 cm); 4 = foliated metadolerite pebble in Hole 1114A (Sample 180-1114A-36R-1, 70-72 cm).
