Rubid strontium and uranium lead
would you use uranium-lead radiometric dating to finnd an igneous rocks age
An accurate radiometric date can be obtained only if the mineral remained a closed system during the entire period since its formation this is why radiometric dating can't be used with accuracy.
Time since metamorphism.
The age of the Solar System HAS TO BE at least as much as that of the oldest rocks found on Earth, other planets, or asteroids (if you assume that those rocks come from the Solar System) - and that's what has been found. And that's the approximate age of the oldest rocks found. The main methods used rely on radiometric dating. For more information, check the Wikipedia (or other sources) for:* Age of the Earth* Radiometric dating
radiometric dating is base on the half life of the radioactive atoms

Igneous rocks
Radiometric dating of moon rocks from the maria indicate that they formed about 3.16 to 4.2 thousand million years ago.

They can use either radiometric dating or magnetostratigraphy.
Radiometric dating is the principal source of information about the absolute age of rocks and other geological features, including the age of the Earth itself, and can be used to date a wide range of natural and man-made materials.
Carbon 14 dating is the best known example of radiometric dating, but there are many others. Another example of radiometric dating is the dating of the age of geological formations on earth. The oldest known rocks on the earth that have been analyzed, have been dated back some 4.404 billion years.
An accurate radiometric date can be obtained only if the mineral remained a closed system during the entire period since its formation this is why radiometric dating can't be used with accuracy.
