Uranium 238 used for dating rocks

Three of the most clever techniques utilize uranium, volcanoes, and trapped electrons. Did you know that scientists can tell how old a cave painting is by dating the rocks on top of or underneath it? Like radiocarbon dating , Uranium-series U-series methods rely on radioactive decay. Scientists have learned how long it takes the above isotopes to decay: U has a half life the time it takes for half of a sample to decay of 4. Therefore, by measuring how much of the parent and daughter isotopes of uranium remain in a sample, scientists can determine how old it is.

Absolute dating allows scientists to assign numbers to the breaks in the geologic time scale.

Of all the isotopic dating methods in use today, the uranium-lead method is the oldest and, when done carefully, the most reliable. Unlike any other method, uranium-lead has a natural cross-check built into it that shows when nature has tampered with the evidence. Uranium comes in two common isotopes with atomic weights of and we'll call them U and U.
