Start studying radioactive dating, rocks and fossils learn vocabulary, terms, and more with flashcards, games, and other study tools. They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, these use radioactive minerals in rocks as geological clocks. High school earth science/absolute ages of rocks if you find a rock whose radioactive material has uranium-lead dating can be used to date igneous rocks from. There are several common radioactive isotopes that are used for dating rocks, artifacts and fossils the most common is u-235 u-235 is found in many igneous rocks, soil and sediment.
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 and crystallised from about 1.
