The Peru–Chile Trench, the forearc and the western edge of the central Andean plateau (Altiplano), delineate the dramatic "Bolivian Orocline" that defines the Andean slope of southern Peru, northern Chile, and Bolivia.

Peru-Chile Trench, submarine trench in the eastern Pacific Ocean, about 100 miles (160 km) off the coast of Peru and Chile. It reaches a maximum depth of 26,460 feet (8,065 meters) below sea level in Richards Deep and is approximately 3,666 miles (5,900 km) long; its …

2024年1月21日 · The Peru-Chile Trench is an oceanic trench in the eastern Pacific Ocean off the coast of Peru and Chile. It delineates the boundary between the subducting Nazca Plate and the overriding South American Plate. The Bolivian Orocline marks a transition point where the Andes change their orientation.

2023年11月29日 · Some of the most familiar ocean trenches are the result of this type of convergent plate boundary. The Peru-Chile Trench off the west coast of South America is formed by the oceanic crust of the Nazca plate subducting beneath the continental crust of the South American plate.

The Peru–Chile Trench, the forearc and the western edge of the central Andean plateau (Altiplano), delineate the dramatic "Bolivian Orocline" that defines the Andean slope of southern Peru, northern Chile, and Bolivia.

2024年6月6日 · The Atacama Trench, also known as the Peru-Chile Trench, runs parallel to the coasts of Peru and Chile. A 1000-kilometer stretch of the larger 5900-kilometer-long trench runs offshore of the Atacama Desert.

Extending the entire length of South America, the margin is punctuated by the deep Peru-Chile trench where the Cocos, Nazca, and Antarctic plates are converging with and sinking beneath the South American plate.

2020年1月12日 · The Peru-Chile Trench marks the boundary between the two -- the zone where the Nazca Plate disappears. The trench is about 3700 miles long and averages about 40 miles wide. Its deepest spot, known as Richards Deep, bottoms out at a depth of more than five miles.

A comprehensive data set of more than 200 profiles across the Peru-Chile Trench between 4° and 45°S is used to describe the morphology and shallow structure of the trench axis and the downbending oceanic plate just prior to subduction.

2022年1月25日 · The abyssal canyon, also known as the Peru-Chile Trench, was created by the subducting of the Nazca oceanic plate underneath the South American continental plate. It extends for 5,900...
