Xenotime (YPO) is an isotopically robust chronometer, which is increasingly being recognized as a trace constituent in siliciclastic sedimentary rocks.It may start to grow during early diagenesis, typically forming syntaxial outgrowths on detrital zircon grains.But there are some questions that come to mind: Calculus students typically meet this problem somewhere in the second semester.It is one of the simplest examples of a differential equation.Of course, there are many problems with such dating methods, such as parent or daughter substances entering or leaving the rock, as well as daughter product being present at the beginning.Here I want to concentrate on another source of error, namely, processes that take place within magma chambers.This technique is generally used to date igneous and metamorphic rock, which are rocks that were once melted due to extreme heat and pressure.
If there were such a pair of isotopes, radiometric dating would be very simple.
Dating the particles which make up the rock wouldn’t give you the age of the rock itself.
In addition, the redeposition process upsets the conditions necessary to achieve accurate results through radiometric dating.
Xenotime has the properties of an ideal U–Pb chronometer, containing elevated levels of U (generally 1000 ppm) and very low concentrations of initial common Pb.
In addition, it has an exceptional ability to remain closed to element mobility during later thermal events, and commonly yields concordant and precise dates.
