Note that the mere existence of these assumptions do not render the simpler dating methods entirely useless.

In many cases, there are independent cues (such as geologic setting or the chemistry of the specimen) which can suggest that such assumptions are entirely reasonable.

The simplest form of isotopic age computation involves substituting three measurements into an equation of four variables, and solving for the fourth.

Whether there's a data point on the Y-axis or not, the Y-intercept of the line doesn't change as the slope of the isochron line does (as shown in Figure 5).

Therefore, the Y-intercept of the isochron line gives the initial global ratio of could be subtracted out of each sample, and it would then be possible to derive a simple age (by the equation introduced in the first section of this document) for each sample.

It is not easily explained, in the general case, in any other way.

The data points would be expected to start out on a line if certain initial conditions were met.

Age "uncertainty" When a "simple" dating method is performed, the result is a single number.

There is no good way to tell how close the computed result is likely to be to the actual age.Now that the mechanics of plotting an isochron have been described, we will discuss the potential problems of the "simple" dating method with respect to isochron methods.The amount of initial wouldn't change over time -- because it would have no parent atoms to produce daughter atoms.It depends on the accuracy of the measurements and the fit of the data to the line in each individual case.) For example, with Rb/Sr isochron dating, any age less than a few tens of millions of years is usually indistinguishable from zero.That encompasses the entire young-Earth timescale thousands of times over." in the decay equation.The better the fit of the data to the line, the lower the uncertainty.
