Discordia Atomica 💯 🎯

: Grains that do not plot exactly on the Concordia curve are called "discordant". The degree of discordance can vary based on the intensity of the heating or fluid access that caused the disturbance.

: This point often corresponds to the age of a later metamorphic event or disturbance that caused the lead loss. Interpretation Guidelines Discordia atomica

: Scientists use mathematical approaches like the "York" or "Ludwig" methods to perform a linear regression of measurements to define the Discordia line. : Grains that do not plot exactly on

In the context of geochronology and U-Pb (Uranium-Lead) radioisotope dating, refers to a straight line on a Concordia diagram that represents a suite of minerals that have lost some of their daughter isotopes (lead) or parent isotopes (uranium) due to a geological event. Discordia atomica
