Toco orogeny

The Toco orogeny was a mountain building affecting the rocks of northern Chile and northwestern Argentina during the Late Carboniferous and Permian. In 1991, researchers Bahlburg and Breitkurz noted that Chilean rocks had a 100 million lull magmatic and metamorphic "lull" from the Silurian to the Carboniferous. They defined the Toco orogeny as the period when active margin conditions returned in the region. [1]
