Dataset description: Geochemistry of authigenic carbonates from Cascadia Margin

Geochemical analysis of authigenic carbonates from the Cascadia Subduction Zone. Powdered carbonate samples for stable carbon (delta-C-13) and oxygen (delta-O-18) isotopes and carbonate phase were analyzed as a proxy for potential fluid sources, and to better understand how process, such as mixing, and oxidation, can alter the initial fluid isotopic composition and the archived fluid-source signature in the authigenic carbonates.
