  • SEDIMENT-HOSTED AU DEPOSITS (MODEL 26A; Berger, 1986) By
    SEDIMENT-HOSTED AU DEPOSITS (MODEL 26a; Berger, 1986) by Albert H. Hofstra, Joel S. Leventhal, David J. Grimes, and William D. Heran SUMMARY OF RELEVANT GEOLOGIC, GEOENVIRONMENTAL, AND GEOPHYSICAL INFORMATION Carlin-type deposits are epigenetic, large-tonnage, low-grade, sediment-hosted disseminated gold deposits. The deposits are known mainly in northern Nevada and northwestern Utah where they are arranged in clusters and belts. The deposits in this region are estimated to contain about 5,000 tonnes of gold, more than half of which (~3100 tonnes) is in the Carlin Trend. Approximately 1,000 tonnes of gold have been produced. Carlin-type gold deposits are one of the most important types currently being mined in the western United States. Many aspects of this geoenvironmental model also apply to distal disseminated deposits as defined by Cox and Singer (1990), Doebrich and Theodore (in press), and Howe and others (1995). Deposit geology Unoxidized refractory ore: Refractory ore consists of variably decalcified, dedolomitized, argillized, silicified, sulfidized, carbonaceous sedimentary rocks that contain disseminated iron, arsenic, antimony, mercury, and thallium sulfide minerals. Base-metal sulfide minerals are rare or absent in most deposits. Although pyrite, marcasite, orpiment, and realgar have high acid-generating capacity, they generally are present in small amounts (much less than 5 volume percent) and are usually disseminated in, or surrounded by, carbonate rocks with high acid-consuming capacity. Zones with 5-50 volume percent pyrite, marcasite, orpiment, or realgar are present in some deposits. Ore is refractory because much of the gold forms sub-micron grains in pyrite and marcasite and because carbon in the rock can extract gold from cyanide solutions.

HICKEY Mineral Deposit Research Unit, University of British Columbia, 6339 Stores Road, Vancouver, British Columbia, Canada V6T 1Z4 Abstract Carlin-type Au deposits in Nevada have huge Au endowments that have made the state, and the United States, one of the leading Au producers in the world. Forty years of mining and numerous studies have pro- vided a detailed geologic picture of the deposits, yet a comprehensive and widely accepted genetic model re- mains elusive. The genesis of the deposits has been difficult to determine owing to difficulties in identifying and analyzing the fine-grained, volumetrically minor, and common ore and gangue minerals, and because of postore weathering and oxidation. In addition, other approximately contemporaneous precious metal deposits have overprinted, or are overprinted by, Carlin-type mineralization. Recent geochronological studies have led to a consensus that the Nevada deposits formed ~42 to 36 m.y. ago, and the deposits can now be evaluated in the context of their tectonic setting. Continental rifting and deposi- tion of a passive margin sequence followed by compressional orogenies established a premineral architecture of steeply dipping fluid conduits, shallow, low dipping “traps” and reactive calcareous host rocks.

Box 1346 Ann Arbor, MI 48106-1346 Copyright ©, 2005 by Michael Walter Ressel, Jr. All Rights Reserved i ABSTRACT Igneous rocks of five ages are present in the Carlin trend, Nevada, and include: 1) Paleozoic basalt of the Roberts Mountains allochthon, 2) the Jurassic (~158 Ma) Goldstrike intrusive complex, which includes the Goldstrike diorite laccolith and abundant dikes and sills, 3) a Cretaceous (112 Ma) granite stock, 4) lavas and intrusions of the Emigrant Pass volcanic field and widespread epizonal plugs and dikes of Eocene (~40-36 Ma) age that range from rhyolite through basalt, and 5) Miocene (15 Ma) rhyolite lava and tuff. Jurassic and Eocene igneous rocks are by far the most important volumetrically and are spatially associated with nearly all ore deposits of the Carlin trend. This study focuses on the field relations, isotopic dating, and geochemistry of Eocene dikes that intrude sedimentary rocks in many deposits of the Carlin trend, because they are the youngest pre-mineral rocks and have simpler alteration histories than other host rocks.

    26 New Data on Minerals. M., 2006. Vol. 41 UDC549.35 NEW DATA ON GALKHAITE Igor V. Pekov, Igor A. Bryzgalov Lomonosov MoscowState University, Department ofMineralogy, Moscow, [email protected] The chemical composition of galkhaite from several deposits (Gal-Khaya, Yakutia, Russia; Khaidarkan, Chauvay, Kyrgyzstan; Getchell, Nevada, U.S.A.) was studied using the electron microprobe. Galkhaite from all these deposits contains species-forming Cs (3.6 - 6.6 wt %) prevailing over thallium (Cs > Tl) in all samples. The miner­ al from Khaidarkan contains up to 1.0 wt. %, from Chauvay - up to 2.9% Ag. Contents of Na, K, Rb, Ca, Sr, Ba, Pb, Cd, Fe, Se, Te in all the studied samples were below detection limits. It is suggested that the empirical formula of galkhaite be calculated on the basis of the sum: (Hg+Cu+Zn+Fe+Ag+As+Sb+S)= 22. The (Cs,Tl) occu­ pancyis 50-100%, and that suggests the refined idealized formula of galkhaite: (Cs,Tl)o.s., (Hg,Cu,Zn)6(As,Sb)4S'2' The influence of conditions of the microprobe analysis on the results for galkhaite and the crystallochemical rea­ son of strong affinity of the mineral to cesium, the indicator role of galkhaite as related to the Cs geochemistry are discussed. The concentration of cesium in the process of formation of hydrothermal arsenic-antimony-mercury mineralization is the main factor limiting the amount of galkhaite crystallized, so that Cs activity may determine the types of mercury ore. 2 tables, 18 references. Galkhaite, (Cs,Tl)(Hg,Cu,Zn)6(As,Sb)4S12' is heavy element surrounded by 12 atoms of sul­ typical mineral of some low-temperature fur, which had not been found by Kaplunnik hydrothermal ore deposits.

  • University of Nevada, Reno Patterns of Lithology, Structure, Alteration
    University of Nevada, Reno 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 A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Geology by Michael D. Cassinerio Dr. John Muntean/Thesis Advisor May, 2010 © by Michael Cassinerio All Rights Reserved i Abstract Few data sets have been published that depict the extent of hydrothermal 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 chapters, investigates several hydrothermal features associated with the high-grade Turquoise Ridge CTGD in the Getchell District. Traditional exploration tools such as patterns of lithology, structure, visible hydrothermal alteration, trace elements, and clay mineralogy are presented in Chapter 1 to test for the presence of haloes that can potentially be used as vectoring tools in honing in on high-grade ore zones at the Turquoise Ridge CTGD. Carbonate staining was utilized to determine differences in carbonate mineralogy associated with more reactive and non-reactive carbonate host-rocks (Chapter 2). Stable isotopes (δ18O and δ13C) are presented in Chapter 3 to test for the presence of potentially more pervasive cryptic alteration haloes relative to visible hydrothermal alteration and trace element anomalies. Closely-spaced diamond drill holes along two cross-sections across the High Grade Bullion (HGB) ore zone at the north end of Turquoise Ridge were logged in detail.
