800 million years old - Scientists discover 'fingerprints' of supercontinent Gondwana in ancient rocks
2+ day, 16+ hour ago (286+ words) Gondwana is an ancient continent which scientists have now confirmed was a supercontinent that spread over 80 per cent of the landmass on Earth. They found 25,000 ancient rocks, and AI helped them determine that they belonged to Gondwana 500 million years ago....
NASA Earth Observatory Highlights Vasquez Rocks’ Geology Using Landsat 9 Imagery
5+ day, 1+ hour ago (301+ words) NASA releases stunning Landsat 9 multispectral imagery of California’s Vasquez Rocks, revealing deep geological and ecological data. NASA’s Earth Observatory has published high-resolution Landsat 9 imagery detailing the stark, otherworldly geology of California’s Vasquez Rocks, a dramatically tilted sedimentary formation internationally recognized…...
USGS and Nebraska Release First-Ever Statewide Map of Surface Geology
1+ week, 5+ day ago (186+ words) RESTON, Va. — The U.S. Geological Survey and the University of Nebraska-Lincoln have released the first statewide map depicting the geology at Nebraska's land surface, closing a long-standing gap in the nation's geologic map coverage. Until now, Nebraska had no modern…...
Decoding Rocks to Reveal What the Critical Zone Hides - Eos
1+ week, 5+ day ago (258+ words) As environmental conditions change, it is increasingly important to understand the structure and properties of the Earth’s critical zone, the layer where rock, soil, water, air, and living organisms meet and interact. While several geophysical methods provide images of the…...
Applied Sciences, Vol. 16, Pages 8652: Basin-Wide Monitoring and PIM Parameter Inversion of Mining Subsidence Using UAV-LiDAR
1+ week, 5+ day ago (473+ words) Accurate, comprehensive, and spatially continuous monitoring of mining-induced surface subsidence is essential for geohazard prevention, ecological restoration, and safe mining. Conventional approaches, however, are limited by the sparse spatial distribution of GNSS observations, the difficulty of InSAR in resolving large…...
Geophysicist identifies a maximum practical viscosity – Physics World
1+ mon, 2+ week ago (332+ words) At what point does a material become so viscous that it cannot flow? The question is a tricky one because some apparently solid objects are not as rigid as they seem. A glacier, for example, may look immobile, but when…...
Flow morphology and patterns in porous media convection: A persistent homology analysis | Journal of Fluid Mechanics
1+ mon, 4+ week ago (627+ words) Published online by Cambridge University Press: 14 July 2026 Note that a slip at the walls is possible, due to the Darcy formulation adopted. Periodicity is considered across the vertical boundaries (directions $x,y$ ) for all flow variables. (i) Semi-infinite domain: the temperature…...
