Rb sr dating problems
This makes mineral isochrons for the Rb-Sr decay sequence rare and is the reason most isochrons in the literature for this dating method use whole-rock isochrons.What are the critical assumptions that go into this dating method?
Like potassium (K), rubidium is an alkali metal and therefore chemically behaves much like potassium.Most readers appreciate the hard science, but many have struggled with the equations.The purpose of this series is to demonstrate in no uncertain terms that these dating methods do not prove that Earth is millions or billions of years old, as is often reported.In any case, there is some uncertainty in one of the critical parameters used by isochron dating models of Rb decay.
A little-advertised characteristic of rubidium-containing minerals is that they are moderately rare in nature.
In addition, Sr produced in this manner to seriously skew the age calculated by this method.
