Three-dimensional electrical conductivity in the mantle beneath the Payún Matrú Volcanic Field in the Andean backarc of Argentina near 36.5°S: Evidence for decapitation of a mantle plume by resurgent upper mantle shear during slab steepening

Southern Mendoza and northern Neuquén Provinces, south of the Pampean Shallow Subduction region in western Argentina, are host to the <2 Myr Payunia Basaltic Province, which covers ∼39 500 km 2 with primarily basaltic intraplate volcanism. This backarc igneous province can be explained by ext...
