What Controlled the Growth of the Southern Central Andes?

by T. Schildgen 15 July 202026 January 2023

Flat-slab subduction appears to have played a minor role in the growth of the Southern Central Andes, with evidence for eastward migrating deformation.

Los Incendios del Amazonas Contribuyen al Derretimiento de los Glaciares Andinos

by Michael Allen 25 February 202021 June 2023

Investigaciones recientes revelan que las emisiones de carbono negro producidas por los incendios en el Amazonas causan que los glaciares en los Andes absorban más radiación solar y se derritan más.
