Proposals for SPECIAL ISSUES
Proposals for SPECIAL ISSUES will be considered if these are agreed with the potential GUEST-editors at least 1 year in advance OF ITS PUBLICATION, IF APPROVED. These must fit within about 75 printed pages (6-8 papers). Contributors must secure funds to support any expanded issue. No guest editor can author or co-author more than one paper in their special issue.
In the proposal, special issue’s title, list of potential articles, outline for each of them, authors and their affiliations, a clear motivation and goals of the proposal, and submission and review time plan should be included. PROCEEDINGS OR CONTRIBUTIONS COMING STRAIGHT FROM A MEETING OR CONFERENCE WILL not be published in Episodes. A special issue should focus on single geologic theme. There should be cohesion or focus to the issue. All each paper should be of broad international interest.
Acceptance or rejection of the proposal entirely depends on evaluation by IUGS Publication Committee. The proposal should be submitted to the Editor-in-Chief of Episodes for being evaluated.
