A team of researchers from China University of Geosciences, has concluded that eclogite samples found at the northern Central Orogenic Belt within the North China Craton, show that modern-type subduction events occurred on ...
NASA's Curiosity Mars rover spent most of March climbing the "Greenheugh Pediment"—a gentle slope capped by rubbly sandstone. The rover briefly summited this feature's north face two years ago; now on the pediment's southern ...
