Are Diamonds Ubiquitous Beneath Old Stable Continents?

by Sergei Lebedev 7 August 20182 March 2023

Although rare at the Earth’s surface, diamonds may be commonplace at depths of 120 to 150 kilometers below the surface within the lithosphere of old continents.

On the Origin of Infragravity Waves

by Terri Cook 23 July 201824 February 2023

Seafloor pressure sensor data show that long-period ocean surface waves radiating from the world’s shorelines are mostly reflected back to shore by the continental shelf edge.

Researchers analyze how low-angle, high-displacement faults influence the evolution of continental rifts.

An Improved Understanding of How Rift Margins Evolve

by Terri Cook 21 March 201829 September 2022

A new seismic reflection study of the mid-Norwegian margin examines the role that low-angle, high-displacement faults play in the evolution of continental rifts.

Erasing a Billion Years of Geologic Time Across the Globe

Lucas Joel by L. Joel 5 February 201823 February 2023

The Great Unconformity—a huge time gap in the rock record—may have been triggered by the uplift of an ancient supercontinent, say researchers using a novel method for dating rocks.

Earthquakes May Prevent Underwater Landslides

by David Shultz 4 April 201621 July 2022

Smaller quakes around the active edge of continental plates may contribute to increased stability by promoting compaction and solidifying the top 100 meters of seafloor sediment.
