Annotated record of the detailed examination of Mn deposits from DSDP Leg 51 (Cores 417A and 417D), DSDP Leg 52 (Core 418A) and DSDP Leg 53 (Core 418B)

The JOIDES Paleoenvironment Panel had noted that the Neogene section had only been spot-cored on previous legs in the Western Atlantic (Legs 1, 2, 4, 11, and 43). The Panel accordingly requested that the complete section be recovered on Legs 51 through 53 in order to examine the transition from sili...

Description
Summary:The JOIDES Paleoenvironment Panel had noted that the Neogene section had only been spot-cored on previous legs in the Western Atlantic (Legs 1, 2, 4, 11, and 43). The Panel accordingly requested that the complete section be recovered on Legs 51 through 53 in order to examine the transition from siliceous, Pacific-type Eocene sedimentation to non-siliceous sedimentation resulting from the gradual emergence of the Central American isthmus. It was also detremined to examine in detail the thick Cretaceous-Tertiary section overlying the basement.
