One form of this process is interpreted using the two intercepts of the discordia and concordia lines, and is often performed on zircon because it rejects lead from its crystal lattice.
One form of this process is interpreted using the two intercepts of the discordia and concordia lines, and is often performed on zircon because it rejects lead from its crystal lattice. Pleochroic halos can be observed using this method, one form of which uses chlorine and is specific to the 1950s. Other forms include samarium-neodymium, rubidium-strontium, and potassium-argon. Another form of this technique uses the fact that, every 5,730 years, half of the carbon-14 nuclei decay away. For 10 points, name this technique, often using uranium-238, that finds the age of an object using radioactive decay rates.
