Tera–Wasserburg diagram

Tera–Wasserburg diagram noun: a type of concordia diagram, used in the context of uranium–lead dating, whose axes are the ratios ²⁰⁷Pb/²⁰⁶Pb and ²³⁸U/²⁰⁶Pb.

Noun

Tera–Wasserburg diagram (plural Tera–Wasserburg diagrams)

  1. 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...
    • One feature of the Tera–Wasserburg diagram is that for samples whose original lead content was both high and of unknown isotopic composition, the plotted points may lie on an isochron whose intersection with the ^{₂₀₇}Pb/^{₂₀₆}Pb axis gives the original lead composition and whose intersection with...

Examples of Tera–Wasserburg diagram in a sentence

  • This can be checked in a Tera–Wasserburg diagram, provided that the zircons belong to a single population, since common-Pb correction should reduce the data to a single point on the concordia.2012, Frank Vanhaecke, Patrick Degryse, Isotopic Analysis, Wiley-VCH, page 252:
