Isochron dating site
A gain moves the point up and a loss moves the point down. A shift from contamination can take place in all of the data points, but such contamination does not affect all data points equally, so it can cause the data points to shift off the true isochron completely.
Given this, when one looks at an isochron plot, how can one really tell where the true isochron line should be?
If there is a gain or loss of daughter isotope the point moves vertically.We have two sources of Y, so y = c1 * x c2 * z at the end of some time period.It follows that the ratios x/z and y/z have a linear relationship whose slope yields the age of the sample.Minerals present in these events contain various radioactive elements which decay and the resulting daughter elements can then be used to deduce the age of the mineral through an isochron.

To view an animation of how an isochron changes over time as decay occurs, see the following website As time progresses and decay occurs, the number of atoms of the parent isotope decreases, and the number of atoms of the daughter isotope.… continue reading »
