Uranium-series dating is a radiometric dating technique used to determine the age of calcium carbonate materials, such as stalactites, stalagmites, and coral. This method relies on the decay of uranium isotopes into a series of daughter isotopes, including thorium and radium, which accumulate over time. By measuring the ratios of these isotopes, scientists can estimate the age of the sample. This dating method is particularly useful for dating geological and archaeological samples that are between 1,000 and 500,000 years old. It provides valuable information about past climate changes and the timing of human activities, contributing to our understanding of Earth's history.
