Speaker:  Dr. Julie Bloxson
Company: Stephen F. Austin State University

Julie received her B.S. in geology from The University of Akron, her M.S. in geology from Kent State University, and her Ph.D. from Case Western Reserve University. For two years, she worked at the Ohio Geological Survey in the Energy Group on subsurface mapping projects that focused on salt deposits, carbon sequestration, and unconventional resources. She is currently an assistant professor at Stephen F. Austin State University and heads the East Texas Core Repository and the Core Lab. This facility focuses on non-destructive core analysis and correlates core data to well log data for better subsurface analysis for natural resources and energy-related issues.


Potential for REEs and Other Critical Minerals in Large Evaporitic Bodies: Examples from North American Phanerozoic Salt Bodies

With the increased demand for rare earth elements (REEs) that coincide with our technological advances, we are looking for new sources. REEs are typically found in alkaline igneous rocks. Yet new potential sources lie elsewhere. Modern seawater contains REEs and other critical elements; extensive evaporitic bodies derived from ancient seawaters could be a potential source. Even at low concentrations, these elements could have commercial value, be useful indicators of palaeoceanographic conditions, and lead to insights in deposition, diagenesis, and halokinesis of salt bodies. Here, we present trace and bulk geochemistry of several large evaporitic bodies in North America: Salina Group, Louann Salt, Hutchison Salt, and Salado Salt. The bulk geochemistry shows that these bodies are primarily halite, with some containing anhydrite, shale laminations, and carbonates. The trace element geochemistry of the salts is highly variable, including REEs concentrations. Across the four evaporite bodies, there are relatively high amounts of Sr (0.0 – 1663 ppm), Fe (0 – 462 ppm), Mn (0 – 208 ppm), Nd (0 – 1237 ppm), Pr (0 – 817 ppm), Ce (0 – 468 ppm), La (0 – 471 ppm), amongst others. The REE enrichment in various samples can be argued to be an indicator of authigenic materials compared to diagenetically altered or weathered evaporite minerals or could be representative of ancient seawater chemistry. However, due to various basin flushing events, using the geochemistry alone for depositional analysis should be taken with a grain of salt. More data are needed to decipher the complex histories of these salt bodies. Overall, if found with high enough concentrations, these salt bodies, often brined for caverns, could prove economically valuable.
