Glacial buzz-saws, gold in fool's gold, fingerprints in sea water, and fluvial iron
Date:10/19/2013

This efficient erosion -- the glacial buzz-saw -- operates best at the snowline where glaciers are thickest and fastest moving. But can glaciers also cut horizontally to create low angle surfaces or plateaus? That's what has been claimed recently to have happened during the Ice Age on the west coast of Norway. We provide evidence that the plateaus have been cut into by and so are older than cirques and valley glaciers. We also find no relationship to cirque distribution or to Pleistocene snowlines. The gentle, high elevation surfaces of this and other glaciated passive margins are largely inherited from Neogene non-glacial, fluvial environments. Yet Pleistocene glacial erosion has done far In Norway than to cut its magnificent fjords -- many hundreds of meters of soft rocks must have been removed from the coastal and inshore zone to account for the huge sediment volumes offshore.


Does gold in orogenic deposits come from pyrite in deeply buried carbon-rich sediments?: Insight from volatiles in fluid inclusions
Damien Gaboury, Laboratoire de Mtallognie Exprimentale et Quantitative (LAMEQ), Universit du Qubec Chicoutimi (UQAC), 555 Boulevard de l'Universit, Chicoutimi, Qubec G7H 2B1, Canada; dgaboury@uqac.ca. Posted online ahead of print 16 Oct. 2013; http://dx.doi.org/10.1130/G34788.1

Orogenic gold deposits form an important class of hydrothermal deposits distributed in metamorphic volcano-sedimentary belts worldwide. It is accepted that gold-bearing fluids are generated by metamorphic dehydration reactions at depth (about 5 to 12 km) following mountain building during tectonic collisional events. However, the source of gold remains speculative and because of that, key criteria for selecting favorable areas for exploration is lacking. Recently, it was proposed that gold in primary nodular pyrite hosted in organic matter-rich sh
