Dear Colleagues, Elements: An International Magazine for Geochemistry, Mineralogy, and Petrology is soliciting thematic proposals for its 2027 publication lineup. The next submission deadline is September 25, 2025 (not 2026, as incorrectly stated in the previous post). Submission guidelines and a proposal template can be found at https://elementsmagazine.org/publish-in-elements/. A thematic proposal is a short document that includes: * Proposed issue title * Proposed guest editor name(s) and full contact information * Overall scope (1–2 paragraphs describing the topic and why it is important to cover in Elements) * Proposed articles (1 introduction + 5 chapters) with brief yet detailed descriptions, proposed authors, and their institutions. Please note that author confirmation is not required for proposal submission. * Summary of related coverage previously published elsewhere, if applicable Questions? Seeking feedback on a draft proposal? Contact editor@elementsmagazine.org<mailto:editor@elementsmagazine.org>. We thank you in advance for your initiative! Best regards, Carol Frost Principal Editor for Geochemistry
