was collected from the only outcrop (exposure) of rock observed on Dive 3464.
The sediments in the area are comrised of coral rubble and foraminifera tests
(see Rock 5). Rock 6 (below) appears to be a loosely-cemented version of the
foram-rich sediment. It crumbles easily and is not nearly as well-cemented as
the foraminiferan limestone found at Barrelfish Cliff, Wreckfish Cave, and Sponge
(scale bar divisions are each 1 cm)
Collected on JSLII Dive 3464, Popenoe Coral Mounds, Blake Plateau (2567 ft).
