The Malargiie fold-and-thrust belt is a thick-skinned one developed in Miocene-Pliocene times during the Andean orogel1y, in Mendoza province, Argentina. It is well known that the tectonics of this mountain chain involves both basement and cover rocks. The former are mainly plutonic and volcanic rocks formed during the Gondwanic magmatic cycle (Carboniferous-Triassic). These rocks fornled the basement of Mesozoic marine and nonmarine sediments in the Neuquel1 basin. Large amounts of Cenozoic sintectonic materials fill the foreland basins related to the Andean orogeny.
