Fossils and geologic time the application of radiometric dating techniques to determine the absolute ages of rocks resulted in the discipline of. Radiometric dating and the geological time scale because of course there are no young-earth radiometric dating methods established (no big surprise there). Relative dating and radiometric dating are used to determine age of fossils and geologic features, but with different methods relative dating uses observation of location within rock layers, while.
