Depth Coverage Base of the crust
Area Western United States (latitude: 25°/50°; longitude: -126°/-88°)
Data Set Description [Schutt et al, 2018] Temperatures are calculated from the Pn tomographic model of Buehler and Shearer [2017]. 95% of Moho temperature estimates are between 444–892 °C, with extrema at 200 and 1160 °C. Temperatures over 800 °C correlate strongly with occurrences of <10 Ma magmatism, suggesting a weak lower crust.
