About Arianna

For shorter timescales, it is unlikely that enough 40 Ar will have had time to accumulate in order to be accurately measurable. This assumption has been shown to be faulty. In uranium-lead U-Pb dating of zircon, the zircon is found to exclude initial lead…. As with any dating technique, there are some significant limitations. The potassium-argon dating method has been used to measure a wide variety of ages. When rocks are heated to the melting point, any Ar contained in them is released into the atmosphere. The calcium-potassium age method is seldom used, however, because of the great abundance of nonradiogenic calcium in minerals or rocks, which masks the presence of radiogenic calcium. The long half-life of 40 K allows the method to be used to calculate the absolute age of samples older than a few thousand years.

When 40 K decays to 40 Ar argon , the atom typically remains trapped within the lattice because it is larger than the spaces between the other atoms in a mineral crystal.
