Snapper closed, but came up empty. None 

 Enough dark brown mud on out- 

 side of jaws for examination. Mud 

 may have been too stiff to allow 

 jaws to grip when the snapper was 

 pulled off bottom

material, probably mostly clay minerals, is present. Feldspar, hornblende, and a few manganese grains 

 also were identified. 



Sample 69. Remains of organisms are fairly common, and include radiolaria, sponge spincules, arenaceous 

 foraminifera, and fish teeth. In addition, the sand grades contain cleavage fragments of brown hornblende 

 (-2V=80), plagloclase feldspar (andesine, Ab60An40), and round manganese grains. 



Sample 70. Sand grades are very small in amount. Remains of organisms are principally diatoms, to- 

 gether with radiolaria, sponge spicules, arenaceous foraminifera, and fish teeth. Round manganese -iron 

 grains of sand size are aiso present. 



Sample 71. Very small, fine-grained sample. Contains very few remains of organisms, chiefly radio- 

 laria. Also contains augite, orthoclase, hornblende, plagioclase (andesine), basic volcanic glass, and 

 manganese.
