Latest Orogeny Stories
A team of Belgian biologists led by researchers at KU Leuven has provided the first genetic evidence that rapid evolution can help non-native plant species spread in new environments.
Highlights include several studies based in the U.S. Sierra Nevada, including a description of "magma fingers" and the formation of granite in the high Sierra crest near Yosemite National Park.
50 million years ago, mountains began popping up in southern British Columbia and swept down Northern America over the next 22 million years, according to Stanford geochemists.
Our research at the State Key Laboratory of Palaeobiology and Stratigraphy, Nanjing Institute of Geology and Palaeontology, has shown, based on a refined division and correlation of the graptolite-bearing strata in southern Jiangxi, China, that the Kwangsian Orogeny commenced in the early Katian Age of the Late Ordovician.
New seismic technique detects boundary between old and new lithosphere.
An international team of researchers has created the most complete seismic image of the Earth's crust and upper mantle beneath the rugged Himalaya Mountains, in the process discovering some unusual geologic features that may explain how the region has evolved.
Intense glacial erosion has not only carved the surface of the highest coastal mountain range on earth, the spectacular St Elias range in Alaska, but has elicited a structural response from deep within the mountain.
By Tanner, Geoff Abstract: None of the major roles assigned to the Highland Boundary Fault, such as a transcurrent fault with an orogen- parallel, sinistral displacement of several hundred kilometres, or terrane boundary, are confirmed.
