Annotated record of the detailed examination of Mn deposits from DSDP Site 99, Leg 11 (Core 99A-1)

The principal objective at this site was the recovery of Mesozoic sediment and a sample of Horizon B (or basement). The location chosen for drilling is about 40 nautical miles southeast of San Salvador in 4914 meters of water. Aside from the possibility of recovering the oldest Atlantic sediment, drilling at this site was expected to produce interesting samples for comparison stratigraphically and lithologically with those of Holes 4 and 5 of Leg 1.
