Determination of the timing of geological events, integrating radiometric dating and relative geological relationships.
A trapped-charge dating method estimating time since suitable mineral grains last received sufficient light exposure. Luminescence measurements and environmental dose rate constrain burial age; incomplete bleaching and mixing can bias it. The measured clock is accumulated trapped charge rather than direct decay of a parent isotope.[ref]
Luminescence dating laboratory by United States Geological Survey. The laboratory describes stored dose, sunlight resetting and age as equivalent dose divided by dose rate.

Geochronology is the scientific discipline that involves studying the age of Earth materials and the timing of geological events. It utilizes various techniques to date rocks, fossils, sediment, and even meteorites to establish a timeline of Earth's history and the evolution of its geological features and life forms. Geochronology employs several methods, including: 1. **Radiometric Dating**: This technique measures the decay of radioactive isotopes within minerals and rocks.
