Mountain building at Atuel river Valley (southern Central Andes, Mendoza province, Argentina) is related to Tertiary Andean orogeny that faulted and folded Permic-Early Triassic igneous basement (Choiyoi Group) and Late Triassic-Tertiary sedimentary cover, giving place to a thick-skinned fold-and-thrust belt known as Malargüe fold-and-thrust belt. At this particular site of Andean Mountain ranges, opposite-vergent thrust systems and triangle zones represents a common feature at deformed sedimentary cover, necessarily related to unexposed basement geometry.
