The percentage of Ar40 is even less for younger rocks. If a date is too old, one can say that the mineral did not melt with the lava.

The four bonds are spread apart as far as they can be from each other. As the magma or lava cools, this path will consist entirely of hot magma or lava, and so the argon will have a free path, and will continue to enter the magma as it cools.

Several laboratories in the world are now equipped to perform a much improved radiocarbon dating procedure. The precambrian rock is less interesting because it could have a radiometric age older than life, but this is less likely for the rest of the geologic column.

Thus crystals, as they form, may have tiny imperfections that accept parent and daughter products in the same ratios as they occur in the lava, so one can inherit ages from the lava into minerals in this way.
