Geochronology (GChron) is a not-for-profit international scientific journal dedicated to the discussion and publication of high-quality research on the physical, chemical, and biological processes used to quantify time in all environmental and geological settings throughout Earth's history.

Journal metrics

GChron is indexed in the Web of Science, Scopus, Google Scholar, etc. We refrain from displaying the journal metrics prominently on the landing page since citation metrics used in isolation do not describe importance, impact, or quality of a journal. However, these metrics can be found on the journal metrics page.

Notice on APC invoices

In accordance with current European restrictions, Copernicus Publications does not step into business relations with and issue APC invoices (articles processing charges) to Russian and Belarusian institutions. The peer-review process and scientific exchange of our journals including preprint posting is not affected. However, these restrictions require that the first contact (contractual partner of Copernicus) has an affiliation and invoice address outside Russia or Belarus.
