Eliwa According to your information above, You have two probabilities as I think: 1- The core in abnormal core-rim structured zircon is xenocryst from surrounding rocks or older rocks .....It cannot be used to accurately date a site on its own.Optically stimulated luminescence OSL dating constrains the time at which sediment was last exposed to light. P eople who ask about carbon 14 C dating usually want to know about the radiometric [1] dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years.These methods can be performed on samples as small as one billionth of a gram; unfortunately, most of these experiments require the utilization of special instruments such as a mass spectrometer and can often be costly to conduct.And though radiometric dating methods are rarely one hundred percent accurate, scientist and researchers are still willing to take the risk, for the sake of science or perhaps pure curiosity.Harm to minors, violence or threats, harassment or privacy invasion, impersonation or misrepresentation, fraud or phishing, show more.

Radiation levels radiometric dating more accurate not remain constant over time.

The possible confounding effects of contamination of parent and daughter isotopes have to be considered, as do the effects of any loss or gain of such isotopes since the sample was created.

It is therefore essential to have as much information as possible about the material being dated and to check for possible signs of Precision is enhanced if measurements are taken on multiple samples from different locations of the rock body.

Alternatively, if several different minerals can be dated from the same sample and are assumed to be formed by the same event and were in equilibrium with the reservoir when they formed, they should form an is used which also decreases the problem of nuclide loss.

Finally, correlation between different isotopic dating methods may be required to confirm the age of a sample.

2- The core itself represents the age of anorthosite, and the rims and homogeneous zircons represent the hydrothermal/recrystallized growth and zircon (It refers to zircon crystallized from, or altered by an aqueous fluid).
