Title: Control of mantle anomalies on volcanism and resources in the Western US, as imaged with MT
Abstract: The western US is geological rich in resources from geothermal to critical minerals. As we continue towards renewable and green energy novel methods for characterization need to be developed. Classically, many of these resources have been discovered by a top-down approach, identifying interesting geologic features and drilling them. However, this method is becoming less efficient. A bottom-up approach characterizes the subsurface from the deep source to the near surface system. As it turns out, the mantle controls how heat and fluids get into the crust and understanding this part of the system could increase efficiency in exploration. The western US has a couple interesting mantle features that appear to dominate where resources are at the surface. In this talk, mantle structures related to subduction on the west coast of the US and in the Great Basin will be introduced and discussed with preliminary interpretations.
Biography: Jared Peacock is a research geophysicist at the Geology, Minerals, Energy, and Geophysics Science Center in Menlo Park, CA. He received his Ph.D. from the University of Adelaide and B.S. and M.S. from the Colorado School of Mines, all in geophysics. Since joining the USGS In 2013, his expertise is in magnetotellurics, focusing on characterizing volcanic, geothermal, and mineral systems in 3D.
