Geology and Mineralogy considered with reference to natural Theology. Rubidium decays to strontium. Purely by coincidence, all of the adjustments for example, current values of decay constants to Patterson's computation have canceled each other out. These cool more slowly and have larger crystals, often forming granite. In fact, some sources say that Sr and Ar have similar mobilities in rock, and Ar is very mobile.

This is when the dinosaurs are assumed to have become extinct. This represents Uranium, which emits a series of particles from the nucleus as it decays to Lead Pb-
For consistency with these early papers, and to avoid the risk of a double correction for the incorrect half-life, radiocarbon ages are still calculated using the incorrect half-life value. We now consider whether they can explain the observed dates.
This could cause trouble for Rb-Sr dating. This is one reason why just reporting the percentage of anomalies has little meaning. It's not as easy as it might sound.
And of course, such isochrons can be falsified by mixings or other problems.
