That encompasses the entire young-Earth timescale thousands of times over.
Isochron methodology Isochron dating requires a fourth measurement to be taken, which is the amount of a different isotope of the same element as the daughter product of radioactive decay.
For brevity's sake, hereafter I will refer to the parent isotope as P, the daughter isotope as D, and the non-radiogenic isotope of the same element as the daughter, as Di.
Miscellaneous notes 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.
The better the fit of the data to the line, the lower the uncertainty.
For further information on fitting of lines to data also known as regression analysis , see: York , a short technical overview of a technique specially designed for assessing isochron fits.
There are minor differences between isotopes of the same element, and in relatively rare circumstances it is possible to obtain some amount of differentiation between them. The effect is almost always a very small departure from homogeneous distribution of the isotopes -- perhaps enough to introduce an error of 0.
In contrast, P is a different element with different chemical properties.
If one of these assumptions has been violated, the simple computation above yields an incorrect age.Tags: Adult Dating, affair dating, sex dating
