Performing numerous isochron plots looking for a « good » one could be outlandishly costly. Simply just one isochron age calls for an extremely multitude of dimensions involving equipment that is rather expensive. In accordance with ICR fund-raising literary works of previously, they invested thousands of dollars to their « Grand Canyon Dating venture » — along with one Rb-Sr isochron age (plus some measurements of other isotopes) to exhibit for this. (While this is certainly a bit extreme, it’s not a relatively inexpensive procedure. )
Further tests would probably supply the result that is same the very first, and there is a rather low possibility of finding a dramatically better plot. Many experts would direct their attention somewhere else (perhaps picking out a dating that is different, or in search of less disturbed examples of exactly the same development), as opposed to using the same thing once more.
Negative email address details are frequently posted. Even if the plot will not produce the age straight, it is feasible to see a great deal information that is useful a brief history associated with test through the information. As an example, see Faure (1986, p. 126).
Finally, & most notably. Then we would not expect any sort of agreement between different methods, results published by different researchers, etc if it were the case that isochron ages were essentially random, fictitious numbers.
