GLOBIGERINA OOZE : nearly one-half of the deposit is made up of Coral fragments, some of them 



attaining a diameter of over half an inch, so that it might almost be called a Coral Mud.

Echinoid spines, Fish otoliths, Coccoliths. 

 Residue : about 25 per cent. : — 



Siliceous Organisms (5 per cent.) : Sponge spicules, Diatoms. 

 Minerals (traces) : one or two small glassy particles. 



Fine Washings (20 per cent.) : amorphous clayey matter, with fragments of siliceous 

 organisms.
