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.
Interglacials provide insights into the impacts of warmer than present conditions in certain regions of Earth.
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.
Scientists use a trio of techniques to resolve the age and duration of rhyolite volcanism of the Salton Buttes.
The suspected sudden collapse of a nearby volcano's flank may have triggered an enormous wave that carried large boulders high onto Santiago Island in Cape Verde, a new study finds.
The shape of deformed sediments at the surface may allow researchers to estimate the cumulative slip along thrust faults such as the Chelungpu fault in Taiwan.

Studying Archean-age gneissic and schistic rocks in northwestern Canada, researchers determined that the source of these rocks formed 4.3 billion years ago.
A researcher proposes a tectonic mechanism that could have helped drive one of the biggest evolutionary events in history: the Cambrian Explosion.
A new tectonic history of the Allegeny-Variscan range.
