When was the first uranium-lead dating method developed?
Quick Answer
It was developed in the early 20th century, with key advances around 1907 to 1911.
The Full Story
Uranium-lead dating emerged as one of the first powerful radiometric dating methods in the early 1900s. Bertram Boltwood’s work around 1907 showed that uranium decays into lead at a measurable rate, allowing geologists to estimate the ages of minerals and rocks. Later refinements by scientists such as Arthur Holmes made the method more reliable and widely used. Today, uranium-lead dating remains one of the most important tools in geochronology.
