Unicorn smt.

The two dredge samples collected from the Unicorn Seamount at greater depths (800-1000 m) contained fragments of glassy, blackish-greysh basalts with rare inclusions of carbonate ooze containing foraminifera; encrusted carbonate ooze and sand; fragments of fine-grained arenites containing abundant well-rounded quartz grains of probable aeolian origin.

Hardground crust incorporating planctonic forams, secondary benthonic (Pyrgo sp. and Miliolidae). Surface colonisation by sponge, bryozoans and serpulids.
