Thermomechanical Modeling Refines Subsurface Mapping of Yellowstone Caldera
Oxytropidoceras posted a topic in Geology
Scientists decipher the magma bodies under Yellowstone Computer modeling shows the presence of a thick crustal transition zone that may control the movement of magma emerging from the Earth's mantle, University of Oregon https://www.sciencedaily.com/releases/2018/04/180416185610.htm The paper is: D. P. Colón, I. N. Bindeman, T. V. Gerya. Thermomechanical modeling of the formation of a multilevel, crustal-scale magmatic system by the Yellowstone plume. Geophysical Research Letters, 2018; DOI: 10.1029/2018GL077090 https://agupubs.onlinelibrary.wiley.com/doi/abs/10.1029/2018GL077090 Yours, Paul H.-
