Uranium—lead datingabbreviated U—Pb datingis one of the oldest  and most refined of the radiometric dating schemes. Uranium–lead dating, abbreviated U–Pb dating, is one of the oldest and most refined of the radiometric dating schemes. It can be used to date rocks that formed. Despite seeming like a relatively stable place, the Earth's surface has changed dramatically over the past 4.
Of all the isotopic dating methods in use today, the uranium-lead method is the oldest and, when done carefully, the most reliable. Radiometric dating. Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks. As each dating method was developed, tested, and improved, mainly sincea vast body of knowledge about the behaviour of different isotopic systems under different geologic conditions has evolved.
Radiometric datingradioactive dating or radioisotope dating is a technique used to date materials such as rocks or carbonin which trace radioactive impurities were selectively incorporated when they were formed. Using relative and radiometric dating methods, geologists are able to answer the question: how old is this fossil?. Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks.
