In this week’s #openaccess paper, Montes et al. use field stations and petrographic, geochronologic, and thermochronologic analyses to update the geologic mapping of central Panama. Their data challenge the widely accepted notion that the Central American Seaway closed in late Pliocene time, and, instead, suggest that the isthmus was an uninterrupted chain above sea level from late Eocene...

Eastward-Dipping Turbidites, Magallanes Foreland Basin, Chile

Eastward-dipping turbidites of the Magallanes foreland basin (Ultima Esperanza District, Chile). Resistant, Cretaceous sandstones cap the steep hillside, with the Rio de Las Chinas cross-cutting the glacially carved valley floor below. In the distance are the high Patagonian Andes, which include the grandiose Torres del Paine...
