Radiometric dating. Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks. Radioactive elements decay. The universe is full of naturally occurring radioactive elements. Radioactive atoms are inherently unstable; over time, radioactive "parent. Radiometric dating works best on igneous rocks, which are formed from the cooling of molten rock, or magma. As magma cools, radioactive parent isotopes are separated from previously formed daughter isotopes by the crystallization process. Ideally, the mineral crystals in igneous rocks form a closed system-- nothing. Radioactive decay occurs at a constant rate, specific to each radioactive isotope. Since the s, geologists have used radioactive elements as natural "clocks" for determining numerical ages of certain types of rocks. Radiometric clocks are " set" when each rock forms. "Forms" means the moment an igneous rock solidifies .
