Abstract:
This dataset contains authigenic uranium and excess manganese concentrations from ODP Site 198-1208 that span ~2.5 to 4.5 Ma. These values give insight into sedimentary redox conditions at the drill site through time.

Methods:
Sample depths, ages, and Th concentrations have been previously published for the Pliocene-early Pleistocene (Abell et al., 2021).
For consistency between datasets, Th is used to correct for the detrital components of Mn and U.
Excess/authigenic components are determined via:
[Mnxs] = [Mnmeas] – ([Thmeas] * (Mn/Th)lith)
[Uauth] = [Umeas] – ([Thmeas] * (U/Th)lith)
where [Mnmeas] and [Umeas] represent the total measured concentration of Mn and U, [Thmeas] indicates the total measured concentration of Th, (Mn/Th)lith is the ratio of Mn/Th in an assumed detrital endmember, and (U/Th)lith is the corresponding ratio for U.
We set (Mn/Th)lith to be approximately 43 using the values from upper continental crust for Mn (600 ppm; Taylor & McLennan, 1995) and fine-grained dust for Th (14 ppm; McGee et al., 2016).
