uraniumthoriumhelium
Uranium-thorium-helium dating is a geochronological method used to determine the age of calcium carbonate materials, such as speleothems (cave formations) and corals. This technique is based on the radioactive decay of uranium-238 and thorium-232 into helium-4. The process involves measuring the accumulation of helium-4 in the crystal lattice of the material, which occurs at a known rate due to the radioactive decay of uranium and thorium.
The method is particularly useful for dating materials that are too young to be accurately dated using
The accuracy of uranium-thorium-helium dating is influenced by several factors, including the initial helium content, the
