For a number of years, GFF has published special thematic issues where all articles concern a common topic or method. Now in June 2018, GFF has published the journal’s first virtual special volume. This means that we have collected a number of articles that have previously been published in various issues by the journal but which belong together thematically. All of these items are made available to everyone without charge for the rest of 2018.
This special issue concerns studies where the authors have used analyses of stable carbon isotopes (carbon-12 and carbon-13) to study stratigraphic relationships between rocks of the Ordovician and Silurian. The relative contents of these carbon isotopes reflect the Earth’s climate, and therefore one can use them to show which rocks were formed during different time intervals. In this way, we and our publisher, Taylor & Francis, would like to showcase one of the journal’s strenghts.
You will find the virtual number here.
