However, as stated by Pourret [18], a majority of the journals in geochemistry also have a green colour according to the SHERPA/RoMEO grading system, indicating that preprint (and the peer-reviewed postprint version) articles submitted to these journals can be freely shared on a preprint server, without compromising authors’ abilities to publish in parallel in those journals. Moreover, Pourret et al. [17] highlighted that the majority of journals in geochemistry allow authors to share preprints of their articles (47/56; 84%).
