concordia diagram

名詞

(geology, geochronology) Any of several types of diagram, used in connection with uranium–lead dating, in which each axis encodes differently sourced information about the radiometric age of the mineral being dated.

日本語の意味

ウラン‐鉛年代測定に関連し、各軸が異なる出所の放射性年代情報（対象鉱物の年代を示す）を表す図表

During the lab session, the students plotted their zircon U–Pb measurements on a concordia diagram to estimate its crystallization age.

実習中、学生たちはジルコンのU–Pb測定値をウラン–鉛年代測定で用いられる、各軸が異なる由来の同位体年代情報を表す図にプロットしてその結晶化年齢を推定した。

意味（1）

(geology, geochronology) Any of several types of diagram, used in connection with uranium–lead dating, in which each axis encodes differently sourced information about the radiometric age of the mineral being dated.

The graphing of concordant U-Pb data on a concordia diagram does not provide any information that is not obvious from the individual U-Pb ages themselves. The principal value of the concordia diagram is its unique ability to yield crystallization ages from open systems.
