The Central Atlantic Magmatic Province is one of the largest volcanic provinces on Earth. Wide-angle seismic refraction data were collected in southern Georgia to help better understand the properties of this magmatism within the crust and mantle. Results from the seismic data were combined with 1-D analytical models of mantle melting to help constrain melting conditions at the time the magmatic emplacement. Together these observations suggest that the magmatism was caused by continental rifting and not by elevated mantle potential temperatures due to a “hot spot.” Click HERE to read the publication.
