Placer Gold Deposits Of Utah PDF Download

Excerpt from Placer Gold Deposits of Utah The most important placer district in Utah is the Bingham district, which produced more than ounces of placer gold. The placers in the Bingham district occurred in thick gravel deposits in Bingham Canyon and tributary drainages and were derived mostly from oxidized copper and lead-zinc-silver ores of Oligocene age. Most of the other productive placers in Utah occur along the major river drainages in the eastern part of the State, where sporadic accumulations of flake gold in sand and gravel bars have been mined. Small placers are found associated with lode deposits in scattered areas throughout Utah. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
