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.
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.
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.
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.
How the very slow moving African Continent, with a lithosphere of quite varied age elements and thickness, has responded to ongoing asthenospheric modification.
A recent paper in Reviews of Geophysics discussed how the mineral composition and microfabric of the continental crust influences its seismic properties.
The importance of relevant and consistent data (as well as more samples) spans discussions of water resources and crustal roots at the IGC.
The Midcontinent Rift has characteristics of a large igneous province, causing geologists to rethink some long-standing assumptions about how this giant feature formed.
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.
Studies of titanium in quartz grains could help scientists gain a better understanding of our planet's shifting surface.
