AbstractNew zircon trace-element concentration data and U-Pb geochronology on gneisses from Colombia’s Central Cordillera at 6°N allow for the recognition of the distinct Anacona suspect terrane ...
Geologists have now provided conclusions regarding the North American Cordillera that they say "are provocative in that they blur the definition of tectonic terranes, showing that many observations of ...
In 1964, an exploratory petroleum well was drilled through one mile of Gulf Coastal Plain sediments in southeastern Alabama. The retrieved core included Silurian to Devonian sedimentary rocks that ...
One of the fundamental premises of geology is that the “key to understanding the future is to understand the past.” In order to forecast how a volcano will behave, geologists must map the deposits ...
Two new papers from members of the MESSENGER Science Team provide global-scale maps of Mercury’s surface chemistry that reveal previously unrecognized geochemical terranes large regions that have ...
Boulder, Colo., USA - In the August 2014 issue of LITHOSPHERE, Steve Israel of the Yukon Geological Survey and colleagues provide conclusions regarding the North American Cordillera that they say "are ...
In the Ordovician, Gondwana in the area of northwestern Argentina and northern Chile had a west-facing active margin. The evolution of this margin culminated in the Oclóyic orogeny at the end of the ...
Two new papers from members of the MESSENGER Science Team provide global-scale maps of Mercury’s surface chemistry that reveal previously unrecognized geochemical terranes — large regions that have ...
