“The results of integrated field mapping and geochronology provide evidence for three major tectonothermal events.”

“In view of the new geochronology, the Finnmarkian Orogeny cannot have played any part in the deformation of the Hellefjord Schist.”

“Large-scale tectonic reconstructions depend on linked and reliable geochronology and palaeomagnetic data.”

“Recently, he published the results of a comparison between radiocarbon dating and a second technique, known as optical dating, carried out by a geochronologist.”

“Another geochronologist on the team has dated two volcanic layers above the unconformity, and they consistently date to just over 2.8 billion years.”

“In turn, the geochronologist relies on the geologist for relative ages.”
