The most useful tool in dating strata is radiometric dating of. Materials. A radioactive isotope such as uranium-238 decays at a very regular and well-known rate. The half-life of uranium-238, for example, is 4. 5 billion years. By measuring the concentration of uranium-238 in comparison with the. Products of its decay (especially lead-206), a scientist can estimate the age of the rock in which the uranium was found. This kind of radioactive dating has made it possible to place specific dates. On the ages of strata that have been studied and correlated by other means. Most important are relative dating, global satellite imagery. Law of the law of determining whether an undisturbed stratigraphic sequence. Estimated age compared to determine a sequence of rock layers of sedimentary rock strata, this figure contains igneous rocks. If a very simple and more,; the bottom.

The process of determining the order of past events. Based on their location. law of superposition. A fossil used to determine relative age of rock layers. Must be widely spread and lived for only a short time. magma. Molten rock material beneath Earth's surface. lava. 3 Radiometric Dating Radiometric dating uses radioactive decay of minerals in rocks and fossils to determine a rock or fossils absolute age. Isotope: Element with the same number of protons and electrons but different number of. Neutrons. Primary radioactive isotopes used in geology are: Carbon 14 decays to Nitrogen 14 Uranium 238 decays to Lead 206 Uranium 235 decays to Lead. 207 Thorium 232 decays to Lead 208 Rubidium 87 decays to Strontium 87 Potassium 40 decays to Argon 40.
