With this issue I end my period as co-editor in chief of the Revista Mexicana de Ciencias Geológicas. Thierry Calmus will remain in charge for a while to help with the transition. The new editors are Ángel Nieto Samaniego and Peter Schaaf. Both have extensive experience as scientific editors and I am confident they will continue to improve the quality of the articles published in our journal as well as providing new ideas and renewed energy to the editorial work.
In the three years I have had the honor of serving as co-editor-in-chief, along with Dr. Calmus have tried to improve the quality of the journal through a better selection of manuscripts and favoring the publication of papers of interest to a broader audience or that have impact on other disciplines. Today our rejection rate is about 50% and we have slightly reduced the number of articles published in each issue. The Revista remains Mexico's first publication in the field of Geosciences based on impact factor (according to the Journal of Citation Report) and H factor (according to SCImago Journal Ranking). In the near future we also hope to start using the online editorial system (Open Journal System) for the reviewing process, which has already been implemented for storing past issues on the UNAM journals website (http://www.revistas.unam.mx/index.php/rmcg).
I take this opportunity to sincerely thank the associate editors for their unselfish work to achieve better publica- tions and the technical editors who have supported us over the years to maintain a high formal quality in each issue of the journal.
