意味（1）

(geology, geochronology) A type of concordia diagram, used in the context of uranium–lead dating, whose axes are the ratios ²⁰⁷Pb/²⁰⁶Pb and ²³⁸U/²⁰⁶Pb.

The axes of the Tera–Wasserburg diagram are the amounts of {₂₀₇}Pb (a stable, radiogenic isotope unconnected with uranium series decay) and {₂₃₈}U (the start of the uranium series decay chain), each adjusted and expressed as ratio to the amount of {₂₀₆}Pb (the stable end product of the uranium series).
