Springer Netherlands. The radiation causes charge to remain within the grains in structurally unstable "electron traps". Accuracy levels of within twenty million years in ages of two-and-a-half billion years are achievable. Generally a shorter half-life leads to a higher time resolution at the expense of timescale. Cambridge Univ. It turns out to be a straight line with a slope of Retrieved from https:
Uranium—lead dating is often performed on the mineral zircon ZrSiO 4though it can be used on other materials, such as baddeleyiteas well as monazite see:
Radiometric Dating: Methods, Uses & the Significance of Half-Life
Primate Cranial Diversity. Email Email is required. This can be seen in the concordia diagram, where the samples plot along an errorchron straight line which intersects the concordia curve at the age of the sample. The abundances of parent and daughter isotopes in a sample can be measured and used to determine their age. Deino, A.
