- W878893326 abstract "The abundance of giant landslides in the region of Cusco, as weil as its slow evolution style, shows that the origin of many of them is related to tectonic and /or lithological factors. A special type of this genetic relationship has been identified in the lower Paleozoic wedges overthrusting Mitu Perrno-Triassic group. A morphological and stru ctural difference exists among the landslides development in the Paleozoic rocks of the sub-Andean region (where the sliding mechanisms are related to erosion and to the conform structures) and those formed in the inter-Andean valley of Vilcanota slopes . ln the upper and intermediate parts of this valley sorne wedges of metamorphic rocks of Paucartambo formation outcrop; thanks to overthrust process. Those wedges, without exception, have evolved toward large scale and slow landslides whose areas in some cases surpassing 5 km, Several of these giant landsJides in overthrust wedges are located in deep depressions; there is not evidence that is due to faulting or subsidence processes. REGIONAL GEOLOGICALSETTING The studied area corresponds to the middle basin of Vilcanota river in the Peruvian southeastern Andes. The outcropping unities are: Paucartambo formation (Siluro-Devonian), Copacabana group (Carboniferous), Mitu group (Permian-Triassic), Huancane formation (Neocomian), and Yuncaypata group (middle Cretaceous) . The predominant structures are Vilcanota, Colquepata and Paucartambo anticlines , which direction is SE-NW. The northeastern part of the zone is covered by a succession of sub -parallel-overthrust following a similar direct ion SE-NW. The main faults families have SE-NW and SW-NE directions . At north-east a N-S family of short folds exits. The overthrust wedges that evolved to giant landslides have a morphological relationship with pre-overthrust depressions (probably glacial basins) and belong to Paucartambo formation -or Urcos formation according to the denomination given by Mendfvil & Davila (1978) -, overlying the Mitu group. Paucartambo formation is composed by series of shale and schist with quartzite levels . This unit is correlated with Ananea formation and with a part of Cabanillas group, as weil as with the Siluro-Devonian series described by Marocco (1978) in Vilcabamba range." @default.
