New Insights into North America’s Midcontinent Rift
The Midcontinent Rift has characteristics of a large igneous province, causing geologists to rethink some long-standing assumptions about how this giant feature formed.
How Do Tropical Forests Slow Knickpoints in Rivers?
Using Puerto Rico's Luquillo Mountains as a case study, scientists use the region's geological history to study how knickpoints—areas where there's a sharp change in the river's slope—move over time.
Insights on Climate Systems from Interglacials
Interglacials provide insights into the impacts of warmer than present conditions in certain regions of Earth.
Geochronology: It's About Time
Chronology is at the heart of all geosciences, but its ubiquity has given it an image of a useful tool rather than a foundational discipline of its own.
