New insights into continental geology

This study is led by Prof. Yong-Fei Zheng at the University of Science and Technology of China. It focuses on the development of tectonic processes along convergent plate margins through inspection of recent advances in the fields of geology, geochemistry, geophysics and geodynamics. These advances are fundamental to our understanding of various phenomena at active … Read more

Researchers discover Archean continental rock

At mid-ocean ridges, upwelling of the hot asthenosphere to the surface of the … Read more

Black Fire Blows Up in New Mexico – Produces Pyrocumulonimbus Cloud and Crosses Continental Divide

By Sara E. Pratt, NASA Earth Observatory May 24, 2022 May 21, 2022. Natural color. (Click image for wide, high-resolution view.) The speed and intensity of the Black fire grew rapidly, producing a pyrocumulonimbus cloud and crossing the Continental Divide, to become the second-largest fire in the state of New Mexico. A raging new wildfire … Read more

Caldera chronicles: Two Ocean Pass, where fish can swim over the Continental Divide | Montana Untamed

Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week’s contribution is from Annie Carlson, research coordinator at the Yellowstone Center for Resources, Yellowstone National Park. The Continental Divide of North America is a crest that stretches from Alaska south through the Canadian Rockies, the contiguous … Read more

Hot springs reveal where continental plates collide beneath Tibet — ScienceDaily

By analyzing the chemistry of over 200 geothermal springs, researchers have identified where the Indian Plate ends beneath Tibet, debunking some long-debated theories about the process of continental collision. In the classic example of mountain-building, the Indian and Asian continental plates crashed – and continue colliding today – to form the world’s largest and highest … Read more

These hot springs reveal where continental plates collide beneath Tibet

Credit: Ping Zhao. In the classic example of mountain-building, the Indian and Asian continental plates crashed – and continue colliding today – to form the world’s largest and highest geologic structures: The Himalayan Mountains and the Tibetan Plateau. Despite the importance of these formations, which influence the global climate through atmospheric circulation and seasonal monsoons, … Read more

Hot Springs Reveal Where Continental Plates Collide Beneath Tibet – Long-Debated Theories Debunked

Pictured is a continuously spouting cauldron of near-boiling water, one of a dozen spanning a 10-acre geothermal field at Mangra in southern Tibet. Helium-isotope geochemistry shows it sits above the northern edge of the Indian plate 50 miles below, where India is underthrusting Asian crust to build the Himalayas and Tibetan Plateau.
