AMES, Iowa – The geologists spoke in apocalyptic terms about Iowa’s distant past: “A rift developed deep in the Earth, magma came up and tried to s…

The Penggongmiao complex pluton, located in the Nanling metallogenic belt of South China, provides a critical record of Early Paleozoic (Caledonian) magmatism, but the genesis and mineralization potential of the biotite monzogranite of the pluton have not been constrained. This study presents new whole-rock geochemistry, zircon U–Pb ages, and Sr–Nd–Hf isotopic data for the Penggongmiao biotite mo…

A mysterious geological structure that resembles a human hand with outstretched fingers has been revealed beneath East Antarctica. The discovery shows the frozen continent still hides many geological secrets.

An Earth scientist reviews Julian Charrière’s new exhibition spanning volcanoes, glacial rocks, and humans’ short yet impactful role in geological time.

A 2020 astronaut photo shows three uniquely colored lakes — Tahoe, Walker and Mono — straddling contrasting biomes on either side of the California-Nevada border.

Folarin Kolawole is one of 15 recipients of this year's National Geographic Society’s Wayfinder Award, which recognizes people whose work is expanding our understanding of the planet and helping to protect its future.

The propagation behavior of hydraulic fractures in laminated shale is governed by the interplay between bedding plane weakness and in-situ stress fields; however, the quantitative effects of operational parameters and geological factors on trans-bedding fracture capability remain not fully elucidated. Large-scale true triaxial hydraulic fracturing experiments were conducted on natural Longmaxi Fo…

By combining seismic, gravity and topographic data, a team of researchers from Italy, Switzerland, Germany and the United Kingdom found that several well-known subglacial basins in East Antarctica are part of a single fan-shaped province whose origins trace back to ancient continental stretching.

The newly designated Joyce Country and Western Lakes Unesco Geopark in Galway and Mayo celebrates a 700-million-year geological history that has produced a unique terrain and rich cultural heritage ‘If you take all these springs together in terms of flow, it’s by far the largest in Ireland, and one of the biggest systems in the world,” said Dr Benjamin Thébaudeau, geologist for the newly designat…

Geologists investigating the Mediterranean have uncovered evidence of an ancient event unlike anything observed in modern times.

If dry land formed before the oceans, and the early seafloor was a solid rocky surface, then where did all the soil, sand, and sediments found in today’s oceans come from? How did these materials end ...

Scientists now believe that Stonehenge's Altar Stone may have been carried partway from Scotland by glacial movement. Researchers at Sheffield Hallam University and Curtin University in Perth, Australia, have developed models indicating Ice Age glaciers could have shifted rocks from Scotland as far south as Dogger Bank in the North Sea. This glacial transport would have occurred during the late D…

A giant fan-shaped network of hidden basins has been discovered beneath East Antarctica, revealing that several well-known subglacial features are actually part of one massive geological structure. The finding sheds new light on Antarctica’s ancient tectonic history and could help scientists better understand how the ice sheet behaves today.

IntroductionLandslide monitoring in steep and vegetated mountainous areas is frequently limited by geometric distortions and temporal decorrelation in SAR observations due to geometric distortions and severe temporal decorrelation, which can significantly reduce the effectiveness of conventional InSAR analyses. In addition, understanding the hydrological mechanisms controlling landslide activity …
