4-4-4-4-4-4-4-4-4-4-4-4-4 From: "Zellmer, Georg" <G.F.Zellmer@xxxxxxxxxxxx> Dear colleagues, This is to let you know that *Journal of Petrology* has (i) expanded its scope to include the *petrology and cosmochemistry of planetary materials*, and (ii) expanded its manuscript types to include *Letters* (up to 4000 words, up to 4 figures that may have multiple panels, free of charge free access for an introductory period). These changes have just been made public in the most recent Editorial: https://doi.org/10.1093/petrology/egab023 *Scope of Journal of Petrology* Journal of Petrology provides an international forum for the publication of the best science related to the broad field of igneous and metamorphic petrology within the Earth and Planetary Sciences. Papers published cover a wide range of topics including: - major element, trace element and isotope geochemistry or cosmochemistry applied to petrogenesis and conditions of formation - geochronology aimed at understanding process rates in petrology - experimental petrology addressing the genesis of Earth and Planetary materials - processes of magma generation, differentiation and emplacement - processes of metamorphism across all scales - solutions to fundamental petrological problems through regional studies of igneous and metamorphic rocks - petrology, origin, and evolution of rocky planetary bodies - theoretical modelling of petrogenetic processes - quantitative studies of rock-forming minerals and their paragenesis *Manuscript Types* Journal of Petrology publishes the following manuscript types: *Original manuscripts* The normal maximum length is 12,000 words excluding abstract, acknowledgments, and references. Authors are encouraged to submit papers that are substantially shorter than the normal maximum length, with supporting material included in a supplement. Longer papers may be accepted, but authors are required to explicitly state why the extended length is justified by the scientific argument presented. *Letters* These are short yet still data-rich articles that reveal fundamental new findings in the field. The maximum length is 4,000 words excluding abstract, acknowledgments, and references. At most four figures may be provided. Supporting material may be included in a supplement. The review of Letters will be expedited, but authors need to outline why the findings merit rapid publication. For an introductory period, all accepted Letters will be freely available to all readers. *Perspectives in Petrology* These are review-style articles focusing on current â??hot topicsâ?? in petrology, written by leading international experts within the field. Submission is by invitation only. Authors wishing to propose a topic for a Perspectives article are encouraged to contact the Perspectives in Petrology Editor, Alasdair Skelton (alasdair.skelton@xxxxxxxxx). *Comments and Replies* Comments will be reviewed and if found constructive will be sent out to invite a reply. Comments and replies will undergo review before decisions are made to accept or decline. *Corrigenda* These provide authors with the means to rectify factual errors in published articles. -- For further information, see the *Information for Authors*, here: https://academic.oup.com/petrology/pages/General_Instructions Finally, the journal now provides more *rapid reviewing and submission to publication times*. First decisions on newly submitted scripts are typically returned in less than 3 months. Average submission to publication times have dropped to about one year, with some papers accepted in significantly less time (within 7 months in some cases). This makes Journal of Petrology particularly attractive for *Early Career Researchers*.
