Annotated record of the detailed examination of Mn deposits from DSDP Leg 32 (Holes 303, 303A, 304, 306, 307, 310, 310A, 311, 313)

The northwestern Pacific Ocean is the largest expanse of old oceanic lithosphere, and so the principal theme of Leg 32 set by the Pacific Advisory Panel was the late Mesozoic history of the Pacific Ocean. The main scientific goals originally set for the leg were to: 1) Determine the development of the very deep sea floor of the western Pacific, including the nature of its basement rocks and the age, lithology, and fossil content of the sedimentary rocks overlying acoustic basement. 2) Establish standard mid-Mesozoic to Recent paleontological-biostratigraphic reference sections for the (present-day) northwest Pacific. 3) Determine the paleolatitude for a specific period of volcanicity on Koko Guyot of the Emperor Seamount Chain.
