1 answer

Radiometric dating primarily provides geologists with information about their ages. This method relies on the decay of radioactive isotopes present in rocks and minerals to determine how long it has been since the rock or mineral formed. By measuring the proportions of parent isotopes and their stable daughter isotopes, geologists can estimate the time elapsed since the rock was solidified or the mineral crystallized.

While radiometric dating does not directly provide information about the mineral composition or specific mineral content, it can sometimes be used in conjunction with other analyses to better understand a rock's history and characteristics.
