Examples
Plotting an isochron is used to solve the age equation graphically and calculate the age of the sample and the original composition.
The age is calculated from the slope of the isochron (line) and the original composition from the intercept of the isochron with the y-axis.
The iodine-xenon chronometer citation is an isochron technique.
