The Geological Magazine was originally established in 1864 and has been published continuously ever since. It covers the whole field of earth sciences, has a worldwide readership and has a particular strength in providing a niche for interdisciplinary papers and papers that would be of interest to geologists from many different specialities. Papers of any length are considered, provided that the length is justifiable.

The Magazine publishes both original and review articles, rapid communications, discussions of papers which have already appeared in the Magazine, book reviews and a list of new publications.
