Study uncovers 900°C heat behind stable continents
Researchers from Penn State and Columbia University have discovered that Earth's stable continents formed through extreme heat exceeding 900 degrees Celsius in the lower crust. This process involved radioactive elements migrating upward to cool and strengthen the landmasses. The findings also offer insights into mineral distribution and planetary habitability.
Scientists discover new golden-tongued lizard in China
Researchers in China have identified a previously unknown species of mountain lizard in the upper Dadu River Valley within the Hengduan Mountains of Sichuan Province. Named Diploderma bifluviale, the lizard features a distinctive wheat-colored tongue and thrives in semi-arid shrublands at high elevations. This finding highlights the region's understudied biodiversity.
Scientists pinpoint tremors beneath Tanzania's Oldoinyo Lengai volcano
Researchers have traced tremor signals deep inside Tanzania's Oldoinyo Lengai volcano, locating them in three dimensions for the first time. The study reveals linked tremors at varying depths, providing insights into magma and gas movement. This unique carbonatite volcano's fluid, cool magma produced unexpected results that could improve eruption forecasting.
New tektites reveal ancient asteroid impact in South Australia
Researchers have uncovered a new field of 11-million-year-old tektites in South Australia, pointing to a massive asteroid impact whose crater remains undiscovered. These unique glass fragments differ chemically and geographically from known tektites, recording an event previously unknown to science. The finding highlights Earth's violent past and aids planetary defense efforts.
