Radiometric dating
Videos
Radiometric dating, radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporate

Ale's Stones at Kåseberga, around ten kilometres south east of Ystad, Sweden were dated back to approximately 1,400 years ago using the carbon-14 method on organic material found at the site.
Apatite crystals are widely used in fission track dating.
Monazite geochronology
Videos
Monazite geochronology is a dating technique to study geological history using the mineral monazite. It is a powerful tool in studying the complex history of metamorphic rocks particularly, as well as

Sample preparation: Thin sections of limestone rocks
