Cross-strike structures controlling magmatism emplacement in a flat-slab setting (Precordillera, Central Andes of Argentina)

Mostrar todas las versiones(2)

Detailed structural, kinematic and geophysical data on the foreland of the Pampean flatslab segment (Hualilán area, Andean Precordillera of Argentina) have shown that cross-strike structures have had an important role in the evolution of this Andean segment since Miocene times. These structures repr...
