What is formed at the intersection of parts of the Nazca and South American lithospheric plates?

The Nazca tectonic plate occupies the southeastern part of the Pacific Ocean floor. It collides with the South American plate along its entire length in the western section of this continent, as a result of which the highest mountains of the Southern Hemisphere, the Andes, are formed. These two plates still continue to move against each other, so high seismicity remains in the Andes and often destructive earthquakes that affect the lives of the local population. Also, valuable minerals come to the surface from the depths.
