The growth of open access publishing in geochemistry

In this communication, we look at Open Access (OA) publishing practices in geochemistry. We examine a list of 56 journals and assess whether Article Processing Charges (APCs) and Journal Impact Factors (JIFs) appear to influence publication or not. More than 40% of articles in 2018–2019 were published OA, and about 70% of that portion in fully OA journals. These had a mean APC of US$ 900, whereas the remaining were published in hybrid journals with a higher mean APC of more than $US 1,800. A moderate and positive correlation is found between the number of OA articles published in hybrids journals and their JIF, whereas there is a stronger positive relationship between the number of OA articles published in fully OA journals and the APC. For OA articles published in hybrid journals, it seems that the proportion of OA articles tends to increase in journals with higher JIF.
