The Society for Sedimentary Geology is an international not-for-profit, scientific society based in the US state of Oklahoma. It is commonly referred to by its acronym SEPM, which refers to its former name, the Society of Economic Paleontologists and Mineralogists.
The society's reason for being is to disseminate scientific information on sedimentology, stratigraphy, paleontology, environmental sciences, marine geology, hydrogeology, and related specialties. Members benefit from both gaining and exchanging information pertinent to their geologic specialties. Information is dispersed via the publication of two major scientific journals, the Journal of Sedimentary Research (JSR) and PALAIOS, and the organization of technical conferences and short courses. It also publishes a monthly magazine for its members, The Sedimentary Record, which is now a diamond open access journal.
