How does radioactive decay determine the age of rocks?

WebImportance of zircon in uranium-lead dating The mineral zircon adds three more fundamental advantages to uranium–lead dating. First, its crystal structure allows a small amount of tetravalent uranium to substitute for zirconium but excludes with great efficiency the incorporation of lead. (It might be said that one begins with an empty box.) WebOften applied to the trace mineral zircon in igneous rocks, this method is one of the two most commonly used (along with argon–argon dating) for geologic dating. Monazite geochronology is another example of U–Pb dating, employed for dating metamorphism in particular.

WebToday, scientists use a variety of techniques to date rocks and fossils precisely. Most often, they measure the amounts of particular radioactive elements—often radiocarbon or potassium—present to determine when a rock was formed, or when an animal or plant died. Some techniques work best with materials millions or even billions of years old. WebFeb 10, 2024 · Other minerals sometimes used for uranium-lead dating include monazite, titanite and two other zirconium minerals, baddeleyite and zirconolite. However, zircon is so overwhelming a favorite that geologists often just refer to "zircon dating." But even the best geologic methods are imperfect.
