Uran thorium dating

U-series dating is a family of methods which can be applied to different materials over different time ranges. Each method is named after the isotopes measured to obtain the date, mostly a daughter and its parent. Uranium—thorium dating is a relatively short-range process because of the short half-lives of U and Th relative to the age of the Earth: it is also accompanied by a sister process involving the alpha decay of U into Th, which very quickly becomes the longer-lived Pa, and this process is often used to check the results of uranium—thorium dating. Uranium—thorium dating is commonly used to determine the age of calcium carbonate materials such as speleothem or coral, because uranium is more soluble in water than thorium and protactinium, which are selectively precipitated into ocean-floor sediments, where their ratios are measured. The scheme has a range of several hundred thousand years.
