G 3 has diverse publication categories in order to take full advantage of the nature of the electronic publication medium, without sacrificing the quality that the community expects to find in a top-rated journal. There are six categories of publication. The first three are recognizable from other journals. The second three are novel and are intended to provide for the specific needs of Earth scientists that are possible in an electronic format and more difficult in traditional paper publication. Articles are recent, previously unpublished results of research that meet the most stringent standards of quality and originality and are of interest to a broad research community.
Letters are short papers that undergo a more rapid review and publication.
Criteria for the acceptance of letters will include extraordinary timeliness and originality. Review Articles are longer papers that are timely and appropriate in the context of recent developments in the fields covered by the journal. Prospective authors of Review Articles should discuss their plans with one of the three Editors prior to writing such an article for submission to G 3 . Technical Briefs report on the development of new analytical methods and technical advances including computer models and methods, databases, and geochemical analytical techniques. Data Briefs consist of previously unpublished data with appropriate documentation accompanied by a minimum of interpretation and discussion.
