Silicification across the Betze-Post Carlin-type gold deposit: Clues to ore fluid properties and sources, Northern Carlin Trend, Nevada
… sources at the Betze-Post deposit, the largest Carlin-type gold system in the world (∼49 million ounces Au), are not well understood. To improve knowledge of ore fluids, the geochemical, textural, and fluid inclusion characteristics of ore, late-ore, and post-ore quartz associated with …

Pyrite geochemistry across the Betze-Post deposit, northern Carlin Trend, Nevada
Petrographic, geochemical, and statistical analyses show that stratigraphy and structural controls promoted ore stage fluid flow. For example, ore stage pyrites occur within brecciated rocks and small-scale fractures within the Wispy Member of the Popovich Formation. Ore stage pyrites have trace …

Assessing the Potential for Carlin-type Gold in Northern Nye County, Nevada
… mapping, this study assesses the potential for Carlin-type mineral systems in northern Nye County. Robust factor analysis (FA) is applied to log ratio-transformed stream sediment geochemical data to identify regional mineralogical processes in northern Nye County, including geochemical patterns …

Geochemistry of Tl and selected elements in four Carlin-Type Gold deposits
<p>Four Carlin-type sediment hosted precious metals deposits and a rhyolite hosted precious metals deposit from the western United States have been analyzed for Ag, Au, Ba, Cu, I, K, Li, Mn, Pb, Rb, Sr, Tl, and Zn, and the relationship between Tl, Rb, and Kin mineralized and unmineralized rocks has …

Thallium Isotope Implications for the Metalliferous Source of Carlin-type Deposits in northern Nevada
The Carlin-type deposits of northern Nevada comprise a world-class accumulation of Au deposits with a characteristic geochemical signature of elevated Tl, As, Hg, and Sb. Three possible sources of Au in Carlin-type systems have been described, and include: (1) leaching of Au from pre-enriched …

Petrology of Mineralized and Non-Mineralized Samples from the Railroad District within the Carlin Trend, Elko, NV
… southwest of Elko,Nevada, is part of the Carlin Trend, an area known from submicroscopic gold deposition.Samples consisted of mineralized and non-mineralized limestone (Devonian DevilsGate Formation), mudstone (Mississippian Webb Formation), sandstone (MississippianChainman Formation), and …

Spatial and Temporal Relationships between Carlin-style Gold and Polymetallic Mineralization at the Deep Cove Gold-Silver Deposit, Lander County, Nevada
… of Lander County, Nevada that contains both Carlin-style and polymetallic mineralization. It has been interpreted as a distal disseminated deposit approximately 1.6 km northeast of the Eocene McCoy Au skarn deposit and adjacent late Eocene quartz monzonite Brown stock. Previous geologic …

Patterns of Lithology, Structure, Alteration, Trace Elements, Carbonate Mineralogy, and Stable Isotopes around High-Grade Carlin-type Gold Deposits: Turquoise Ridge Deposit, Getchell District, Nevada
… features surrounding high-grade ore bodies in Carlin-type gold deposits (CTGDs) in Nevada, making exploration, development, and production difficult, especially where visually unaltered, unmineralized rocks occur in close proximity to ore. This thesis, which is divided into 3 standalone …

Inferring Clonal Dynamics in Blood using Single-Cell Measurements
… disease and CRISPR array repair lineage tracing (CARLIN), using single-cell RNA sequencing. Our gene expression analysis shows that the mutation keeps key signaling and stress-response genes switched on and boosts growth-promoting enzymes, collectively pushing blood production toward the myeloid …

The magmatic-hydrothermal fluid history of the Harrison Pass Pluton, Ruby Mountains, NV: implications for the Ruby Mountains-East Humboldt Range metamorphic core complex and Carlin-type Au deposits
… deposition of >200 Moz of Au in sediment-hosted Carlin-type deposits (CTD's) along four linear trends. Magmatic, meteoric, and metamorphic models have been invoked to explain the origin of fluids and Au for CTD's, but few studies have directly examined the fluids generated by a potential source …

Paragenetic Evolution of the Robertson Deposit: Eocene Intrusion Related Gold Deposit in the Northern Shoshone Range, Nevada
… 5 km north of Pipeline, which is a 20 Moz+ Carlin-type gold deposit in the northern Shoshone Range, Nevada. Carlin-type gold deposits have been the focus of many studies as they represent the second largest accumulation of gold in the world, and a growing body of scientific literature …

Petrogenesis of Eocene-Oligocene magmatism of the Sulphur Springs Range, central Nevada: The role of magma mixing
… Range, Nevada (adjacent to the Au-producing Carlin Trend). Some of the Eocene-Oligocene intrusions and cogenetic volcanic rocks in the range exhibit evidence of magma mixing and invite comparisons with other mineralized, Eocene mixed magma systems like the Bingham porphyry Cu deposit 300 km …

The Potential for Repurposing Disturbed Mining Properties in Nevada as Utility-Scale Solar Facilities
… is also performed on mine sites within The Carlin Trend mining district in northeastern Nevada to estimate the potential return on investment from a subset of potential sites. Nuances to this proposal are also explored from a legislative and regulatory perspective which discover an …

The geochemistry of gold-bearing and gold-free pyrite and marcasite from the Getchell gold deposit, Humboldt County, Nevada
… of pyrite and marcasite from the Getchell Carlin-type gold deposit show that elevated concentrations of a characteristic suite of trace metals correlate with ore-stage pyrite morphology. Secondary ion mass spectrometry analyses revealed a significant positive correlation between As and Au …

Petrography and Field Mapping of Eocene Intrusions and Adjacent Breccia Zones at the Scraper Springs Prospect, Elko County, Nevada
… trend with the northern-most projection of the Carlin trend, approximately 25 miles north of the Dee/Rossi area. The eastern limit of Northern Nevada Rift (NNR) is also considered to border the western margin of the Scraper Springs property. The geology at Scraper is characterized by an exposure …

Time-Space Relationships between Sediment-Hosted Gold Mineralization and Intrusion-Related Polymetallic Mineralization at Kinsley Mountain, NV
Carlin-type gold deposits (CTGDs) in north-central Nevada contain a large endowment of gold, making Nevada one of the world's leading gold producers. Most CTGDs occur in four distinct clusters, known as the Carlin Trend, Cortez, Getchell, and Jerritt Canyon. These four camps of CTGDs are estimated …
