Further evidence comes from the complete agreement between radiometric dates and other dating methods such as counting tree rings or glacier ice core layers.

Many Christians have been led to distrust radiometric dating and are completely unaware of the great number of laboratory measurements that have shown these methods to be consistent.

The advantage of isochron dating as compared to simple radiometric dating techniques is that no assumptions are needed about the initial amount of the daughter nuclide in the radioactive decay sequence.

Indeed the initial amount of the daughter product can be determined using isochron dating.

For rocks that start out with a small concentration of the parent, the daughter/non-radiogenic ratio will not change quickly as compared to rocks starting with a large concentration of the parent.

One of the best known isotopic systems for isochron dating is the rubidium-strontium system.

The change in slope from initial conditions--assuming an initial isochron slope of zero (a horizontal isochron) at the point of intersection (intercept) of the isochron with the y-axis--to the current computed slope gives the age of the rock.

The slope of the isochron, , represents the ratio of daughter to parent as used in standard radiometric dating.

The better the fit of the data points to a line, the more reliable the resulting age estimate.

Since the ratio of the daughter and non-radiogenic isotopes is proportional to the ratio of the parent and non-radiogenic isotopes, the slope of the isochron gets steeper with time.
