2019 Publications

Utah Geological Survey Bulletin:

The area around the FORGE site is among the most intensely studied portions of the Basin and Range. In support of the FORGE project, a significant amount of new information has been collected. The results of these studies will be of use to scientists investigating a broad range of geological, geochemical, geophysical topics as well as those interested in EGS development. The Utah Geological Survey volunteered to produce publication that captured the results of research at the Utah FORGE site during Phase 2B, 2018.  Fourteen papers have been contributed to this special publication.
