Formerly Geologiska Föreningens i Stockholm Förhandlingar. GFF is the journal of the Geological Society of Sweden. It is an international scientific journal that publishes papers in English covering the whole field of geology and palaeontology, i.e. petrology, mineralogy, stratigraphy, systematic palaeontology, palaeogeography, historical geology and Quaternary geology. Systematic descriptions of fossils, minerals and rocks are an important part of GFF's publishing record. Papers on regional or local geology should deal with Balto-Scandian or Northern European geology, or with geologically related areas. Papers on geophysics, geochemistry, biogeochemistry, climatology and hydrology should have a geological context. Descriptions of new methods (analytical, instrumental or numerical), should be relevant to the broad scope of the journal. Review articles are welcome, and may be solicited occasionally. Thematic issues are also possible. The journal emphasizes high quality and informative illustration, in both line drawings and photographs.
