Figure 1: Along-axis seismicity of ultraslow-spreading ridges. (1) Earthquakes reach maximum depths of 35 km below the sea floor in areas with peridotite exposure, surpassing by far the deepest known ...

Seismic investigations from the Qinling-Dabie-Sulu orogenic belt in eastern China suggest that this region was affected by extreme mantle perturbation and crust-mantle interaction during the Mesozoic ...

New images from the North Sea show never-before-seen landforms that were carved by a single, colossal ice sheet 1 million years ago and subsequently buried beneath a thick layer of mud. When you ...

For the last decade, metamorphic geologist Tim Johnson at Curtin University in Australia has pondered the first billion years of Earth’s roughly 4.5 billion-year existence. His work takes him to the ...

Scientists have long speculated about why there is a large change in the strength of rocks that lie at the boundary between two layers immediately under Earth's crust: the lithosphere and underlying ...
