When was potassium argon dating first used

Scientists now have accurate methods (see below ) for dating fossils.methods rely on characteristic faunal and geological patterns to bracket the period when the fossil existed.

This is an informational tour in which students gain a basic understanding of geologic time, the evidence for events in Earth’s history, relative and absolute dating techniques, and the significance of the Geologic Time Scale.

Argon is an inert, colorless and odorless element — one of the Noble gases.

Working concurrently and in communication with Lord Rayleigh (John William Strutt), Scottish chemist William Ramsey identified and described the mysterious gas.

The two shared the Nobel Prize in Chemistry in 1904 for the discovery.

Rayleigh and Ramsay discovered argon by the fractional distillation of liquid air.
