Geoscientists Uncover Crustal Dripping in Turkiye's Central Anatolian Plateau
Sep 25, 2024 (SPX)
The study highlights that experimental simulations, coupled with various geological, geophysical, and geodetic data, provide an explanation for the basin's subs...
New study suggests Earth's mantle is more chemically uniform than previously thought
Sep 20, 2024 (SPX)
The research suggests that Earth's mantle is more homogeneous than scientists had previously assumed. The differences in lava composition observed at the surfac...
Two epicenters led to Japan's violent Noto earthquake on New Year's Day
Aug 23, 2024 (SPX)
Geologists have now discovered that the earthquake began almost simultaneously at two different points on the fault, allowing the seismic rupture to encircle an...
Record-breaking Nepali teen eyes final 8,000-metre peak
Aug 21, 2024 (AFP)
With 13 of the world's highest peaks already behind him, he is now one summit away from becoming the youngest person to conquer all 14 mountains towering above ...
Insights challenge prevailing theory of continental formation
Aug 06, 2024 (SPX)
A recent paper by David Hernandez Uribe of the University of Illinois Chicago, published in *Nature Geoscience*, brings new data into the debate, challenging th...
High-pressure silica mineral in the deep Earth found to be anhydrous
Jun 27, 2024 (SPX)
Recent research has indicated that SiO2 stishovite retains significant water content (>1 wt%) and is considered a potential major water carrier in the lower man...
Life on the Ring of Fire: How Taiwan prepares for quakes
Apr 04, 2024 (AFP)
Taiwan sits on the "Ring of Fire", an arc of intense seismic activity along the Pacific Rim, and -- much like neighbouring Japan -- has a long history of catast...
Scandinavia's geological roots trace back to Greenland
Mar 22, 2024 (SPX)
These traces were found in the mineral zircon, which after chemical analyses, indicated to researchers from the Department of Geosciences and Natural Resource M...
Mars' volcanic activity suggests Early crust recycling
Feb 20, 2024 (SPX)
Mars, known for its striking red surface and absence of plate tectonics, has long intrigued scientists with its volcanic features. While the Red Planet's shield...
