Carlin Trend, shown with other alignments of sediment-hosted gold deposits in Nevada.Source: USGS. Newmont's Gold Quarry mine in 2009, on the Carlin Trend. The Carlin Unconformity or Carlin Trend is a geologic feature in northeastern Nevada which represents a period of erosion or non-deposition likely associated with a collision between a tectonic crustal block called a terrane and the North ...
Source: USGS Goldstrike (Post–Betze) Mine, Carlin Trend, Nevada, the largest Carlin-type deposit in the world, containing more than 35,000,000 ounces of gold. [1] Carlin-type gold ore from the Twin Creeks mine, Nevada, near the Getchell Mine. This is an auriferous, silicified-decalcified siltstone/mudstone from the Comus Formation (Lower ...
Production from the trend surpassed 50,000,000 troy ounces (1,600 t) of gold in 2002. The Carlin and other mines along the trend pioneered the method of open-pit mining with cyanide heap leach recovery that is today used at large low-grade gold mines worldwide. New ore deposits are still being discovered and developed along the trend.
Over 200 million ounces of gold are known to be distributed in more than 100 Carlin-type deposits. [citation needed] The Carlin trend extends from the Pinon Range to the Tuscarora Mountains, an area 70 miles long and 10 miles wide. Epithermal, skarn, vein and Carlin-type deposits are also found in the neighboring Battle Mountain-Eureka trend to ...
The late George Carlin is widely regarded as one of the best comedians of all time. And this week, the entertainer—who died in 2008—got an unexpected turn in the public eye with an hour-long ...
The Goldstrike mine adjoins Newmont Mining's Carlin mine complex. Goldstrike is northwest of the Carlin mine on the Carlin Trend. [5] Like most Carlin type gold deposits in Nevada the gold was epithermally deposited in carbonate or silicate sedimentary rocks. The heat source was magmatic but the exact mechanism is still under debate. The Betze ...
