Optical dating is a method of determining how long ago mineral grains were last exposed to daylight. It is useful to geologists and archaeologists who want to know when a particular event occured.

Current carbon dating processes require researchers to ... interacts with the carbon dioxide inside a 1-meter-long optical cavity with highly reflective mirrors on each end. As the light ...

Handprints and footprints 20,000 years old reveal that people lived on the Tibetan plateau at the height of the Ice Age - 16,000 years earlier than scientists had thought. The newly found signs of ...

Researchers have used a new optical dating technique to directly constrain the age of prehistoric stone artefacts from an archaeological site in southern Tibet. The findings are more than 5,000 ...

The age of the cave sediments was constrained via optical dating techniques, which is crucial to help piece together the sequence of climate events leading to a warming planet. The results are ...

A new approach to cavity-ringdown optical spectroscopy could offer a faster, cheaper and highly sensitive alternative to the conventional method for carbon dating. Developed by researchers in Italy in ...
