Models of the early diagenesis of neodymium and its radiogenic isotope at deep-sea site HH3000, Oregon margin, Northeast Pacific

Outputs of the early diagenetic model for neodymium and its radiogenic isotope at deep sea station HH3000 (3060 m, 43°52'N, 125°38'W) from the Oregon margin, Northeast Pacific.

Three types of models are included, and the files are named as following:

1. Baseline simulations, "HH3000Nd.baseline.copre_output.xlsx" for the co-precipitation formulation, and "HH3000Nd.baseline.revscan_output.xlsx" for the reversible scavenging formulation.

2. Sensitivity tests of silicate dissolution rate: "HH3000Nd.{mineral}.{dissolution rate}_output.xlsx", where {mineral} can be "Basalt", "Plag" (plagioclase), "Cpx" (clinopyroxene) or "Chl" (chlorite), and {dissolution rate} can be "1e0" to "1e5", referring to the order of magnitude reduction of dissolution rate relative to the laboratory-derived rates.

3. Sensitivity tests of authigenic clay precipitation rate: “HH3000Nd.basalt.{precipitation rate}.illite_output.xlsx", where "{precipitation rate}" can be "no", "slow", "normal", or "fast".

Explanations of the modeled variables in the above files can be found in "model variable note.xlsx".
