How radiometric dating is used to determine the ages of rocks

Most absolute age determinations in geology rely on radiometric methods. The earth is billions of years old. The main condition for the method is that the production rate of isotopes stays the same through ages, i. The production of isotopes from chemical elements is known as decay rate and it is considered a constant. Because it is driven by sun activity it was always questioned.

Radiometric Age Dating - Geology (U.S. National Park Service)

The age of a rock is determined by stratigraphy , a branch in geology which studies the chronology of events and changes, along with the development of organisms, which have determined the development of the Earth from when it became an independent spatial body until today. The age, or the chronology of geological creations and events is determined using relative and absolute age. In determining the relative age of a rock, the data from sedimentary rocks are generally used. Relative age of magmatic and metamorphic rocks is determined according to their relation with sedimentary rocks. The determination of the relative age of a rock is based on the principle of original horizontality of the sediments, principle of superposition, principle of original lateral continuity, principle of cross-cutting relationships, principle of inclusions, principle of biological succession and the lithology of a rock.

Earth's Creation and the Concept of Deep Time. The Principle of Superposition tells us that deeper layers of rock are older than shallower layers. Principle of Cross-Cutting tells us that the radiological colored granite must be older than the darker basalt dike intruding the granite.
