Nevada, provide a guide for reconstructing Eocene crustal structure ~50 km to the west near the Carlin trend of gold deposits. The deep crustal rocks, in the footwall of a west-dipping normal-sense shear system, may have underlain the Piñon and Adobe Ranges about 50 km to the west before Tertiary extension, close to or under part of the Carlin ...

Abstract. The Carlin trend contains the largest concentration of Carlin-type gold deposits in the world. Two major controversies about these giant gold deposits have …
The Eocene epoch in the Great Basin of western North America was a period of profuse magmatism and hydrothermal activity. During that period, the Carlin-type gold deposits in Nevada were produced ...
Nevada's Carlin Trend is home to high-grade, multi-million-ounce deposits — the elusive elephants of the gold mining industry. These are the giant gold deposits that put Nevada on the map as ...
Interstate 80 between Elko and Carlin, Nevada, follows the valley of the Humboldt River. The Humboldt drains a 17,000 square mile basin along its 275 mile course, located entirely within the State of Nevada. While barely a trickle of water in late summer, spring floods may swell the river well over its banks.
The Carlin Trend, where Nevada's great gold-mining boom began, is on track to produce its 100-millionth troy ounce of gold during 2022, and will likely reach its 150-millionth troy ounce in 2042. By then, Nevada will have cumulatively produced well over 300 million troy ounces …
The mineral deposits along the Carlin Trend form a suite of deposits known as Carlin-type. Carlin deposits comprise stratabound disseminated gold mineralization hosted by Silurian-Devonian carbonate rocks that have been metamorphosed to varying extents. ... On July 1, 2019, Barrick's Goldstrike and Newmont's Carlin were contributed to Nevada ...
a spectrum of Carlin trend deposit types is categorized to illustrate the relative influence of structural and stratigraphic controls on each deposit. REGIONAL GEOLOGIC SETTING The Carlin trend is a 38-mile (60-km) long north-northwest alignment of predominantly carbonate-hosted gold deposits located in northeastern Nevada (figs. A-1 and A-2 ...
Sedimentary platform rocks in northern Nevada serve as hosts for the bulk of the gold in Carlin-type gold deposits. These deposits largely account for this region comprising the most significant gold province in North America. The most prolific part of the Carlin trend is the northern half, which extends from the Gold Quarry Mine on the south ...
Carlin-type deposit known, in the north-central Carlin trend, Nevada document that the orebody is composed of individual high-grade oreshoots that contain different geologic, mineralogic, and textural characteristics. The orebody is typical of many structurally controlled Carlin-type deposits, and is hosted in thin-bedded, impure carbonate or limy

A study of the North Bullion Carlin system, a Nevada Carlin-type gold prospect located on trend with the large Carlin-type gold deposits (CTGD) of the Carlin Trend, identified characteristics of ore and alteration mineralization, mineral paragenesis, and pyrite and whole rock geochemistry that are similar to characteristics that typify …
The Carlin Trend is one of the world's major gold provinces with more than 80 Moz of gold production and reserves. Location of the Star Lake project along the projection of the …
The Carlin Trend was created by upsurges of magma that left sediment rich with metal deposits near the earth's surface. Today, this part of Northern Nevada is one of the world's largest gold-mining regions, the …
found along the Carlin-trend and elsewhere in north-central Nevada (Thorman and Christensen, 1991). There are several hundred million ounces of known and inferred gold in the northern Great Basin, of which over half is contained in the Carlin-type deposits, most along the Carlin trend. About 114 (table 1) sedimentary rock-hosted deposits have been

THE 60-KM-LONG Carlin trend is the most important of sev-eral major gold-producing areas of north-central Nevada and contains the greatest concentration of Carlin-type …
Abstract. A new type of gold occurrence recently discovered in the Carlin trend, north-central Nevada, is clearly distinct from classic Carlin-type gold ore. These occurrences are interpreted to be of sedimentary exhalative (sedex) origin because they are stratiform and predate compaction and lithification of their unaltered Devonian host rocks.

Carlin-type gold deposits contain "invisible" or microscopic particles of gold that are deposited within a mineral called pyrite in sedimentary rocks. Needless to say, these deposits are named after the discovery of the Carlin Gold Deposit in 1961, which was the first of its kind. Today, Carlin-type deposits make up the bulk of Nevada's ...
youngest ore-bearing rocks of the trend (Ressel et al., 2000a, b). The Carlin trend and Carlin-type deposits have been in-tensely studied for about 40 years (Hausen and Kerr, 1968; Radtke et al., 1980; Bakken, 1990; Kuehn and Rose, 1992; Igneous Geology of the Carlin Trend, Nevada: Development of the
A compilation of previously published chemical analyses of 440 stream sediment samples and 115 rocks from two 7 1/2-minute quadrangles, as well as new chemical analyses of approximately 1,000 drill core samples in a 1,514 m (4,970 ft) hole through the Rodeo Creek deposit were used to construct three-dimensional element distribution models that ...
The geochemical character of young, unconsolidated, postmineral deposits that cover mineralized rocks on the Carlin trend partly results from mineralized sources along the trend. Concentration of As in the Miocene Carlin Formation shows an exceptionally well developed progressive increase to about 30 ppm As as altered rock …
The Carlin trend is a 60-kilometer-long line of predominantly sedimentary-rock-hosted gold deposits, which has already yielded 477 tonnes of gold production from …
Carlin Map. Carlin is a city located near the western border of Elko County in northeast Nevada, 23 miles (37 km) west of the city of Elko. It is part of the Elko Micropolitan Statistical Area. Carlin sits along Interstate 80 at an elevation of approximately 4,900 feet (1,500 m). As of the 2000 census, its population was 2,161.
A gold property located about 35 km N of Carlin. Mine is a large open pit, overall 2,000 m long, 500 m wide and up to 200 m deep, comprised of four connected pits (West, Main, South & East). Estimated total production is just under 4,000,000 Troy Oz. of gold. Owned by Newmont Gold Co.
Mining of Carlin-type gold deposits in Nevada has made the United States one of the leading gold producers in the world for almost four decades. These deposits …
The new semi-autogenous mill complex currently (1992) processes more than 28,000 short tons per day. In 1989, the Gold Quarry pit was producing 60% of the total material mined and 62% of the Au recovered by Newmont. A total of 300 hourly and salaried people were employed in the Gold Quarry Mine operations group.
The Goldstrike property is located close to the rifted margin of the North American craton, along an inferred deep crustal structure. Stratigraphy at Goldstrike consists of lower Paleozoic sedimentary rocks, including an autochthonous, miogeoclinal carbonate sequence and an allochthonous eugeoclinal siliciclastic sequence, separated by the …
