      Sediment-hosted gold deposits The Carlin, Cortez, Independence, and Battle Mountain- Eureka gold trends in northern Nevada are defined by the only major sediment-hosted gold deposits in the American Cordillera, although small deposits of this type are also part of the Bingham district, Utah, farther east (Fig. 3). Sediment-hosted disseminated gold deposits in NW Sichuan China have many features in common with the well-known Carlin-type deposits in the western United States. They are hosted by Middle–Upper Triassic turbidites composed of – m of rhythmically interbedded, slightly metamorphosed calcareous sandstone, siltstone, and slate. The ore.

    new gold deposits. The objectives of this paper are to provide an update on gold deposit models, and what new approaches and techniques can now be used to find gold deposits. Gold occurs in a wide range of deposit types and settings, but this paper is concerned with deposits in which gold forms the main economic commodity or a co-product. The Timok Magmatic Complex (TMC) is a well-endowed mineral district in Serbia that hosts world-class Cu-Au porphyry (Majdanpek, Veliki Krivelj, Borska Reka) and high-sulfidation deposits (Bor, Čukaru Peki). Recent exploration activities on the northwestern margin of the TMC have led to the discovery of the Bigar Hill sediment-hosted disseminated gold deposit .

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, tonnes of gold, more than half of which (~ tonnes) is in the Carlin Trend.

Approximately 1, tonnes of gold have been produced. Carlin-type gold deposits. The Eocene of northeastern Nevada is distinguished by the inception of Cenozoic magmatism and extension and the formation of the huge Carlin-type gold deposits.

This field trip ex. The most prolific of these trends, the northern Carlin trend, contains the largest and most productive Carlin-type gold deposits (CTDs), which are demonstrably Eocene (~.

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 been their age, which is.

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. Download PDF The New Year S Floods In Western Nevada book full free.

The Carlin-style gold deposits were defined as a new type after their discovery near Carlin in Nevada, USA during s (e.g., Cline et al., ; Muntean and Cline, ; and references therein).Current Au endowment of Carlin-style deposits in Nevada is estimated up to 7, tons, and the deposits account for ∼ 6 % of the annual global.

sedimentary rock-hosted gold deposits in P.R. China. These breccia bodies are conformable with stratigraphic units in the host rock. An example of this is the Shuangwang gold deposit (Fan, S.C. and Jin, Q.H., ), which is a large Carlin-type gold deposit in the Qinling area, hosted by stratabound breccia bodies (fig.

29). The Suzdal deposit is located on the northwest flank of the Western Kalba gold-bearing belt (), in which tens of gold deposits and hundreds of gold occurrences of different types are hosted in carbonaceous black shale and clastic rocks of Сarboniferous belt strikes NW–SE for more than km and has widths ranging from 30 to km.

sediment-hosted. Sediment-hosted gold deposits are recognized in the Great Basin province of the western United States and in China along with a few recognized deposits in Indonesia, Iran, and Malaysia. Three new grade and tonnage models for sediment-hosted gold deposits are presented in this paper: (1) a general sediment-hosted gold type model, (2) a Carlin.

Much of this gold is being produced from sediment-hosted disseminated gold deposits. Many geologists call these deposits Carlin-type (Berger and Bagby, ) after the mine of the same name in Nevada.

The Carlin mine was discovered in by Newmont Exploration Limited (Roberts, ) and subsequently was used to. tion of gold deposits. The purpose of this paper therefore is to present a summary of the geological attributes of commonly recognized types of bedrock gold deposits and to present a workable geological classifica-tion, highlighting the role of geochemistry in determining each of the deposit types.

Folowing concepts proposed on the relationship of gold and silver mineralization to windows through the Palacozoic Roberts Mountains thrust fault in north-central Nevada (Reboerts, ), Newmont conducted an exploration proramme in the Tuscarora Mountains north of Carlin, Nevada, that resulted in the discovery of the Carlin gold deposit in.

In this study, our team takes a new approach: we are elucidating the genetic relationships between Carlin-type gold and Eocene magmatism in the Battle Mountain district, where there are magmatic-hydrothermal gold skarn and porphyry deposits, Carlin-type gold, and distal disseminated deposits with hybrid characteristics that may be the missing.concentration of metals (especially gold and silver) in near-surface environments, provides an overview of the systematics of the most important approaches to the study of epithermal ores and processes, and summarizes the geology of both sediment-hosted and volcanic-hosted epithermal precious-metal deposits.The Sulphur Spring Range is ∼80 km south of large gold deposits in the Carlin Mineral Hill district, on the west side of the range, and the Union district, on the east side, were mined in the late s to early s for gold, silver, and copper (Lincoln, ).Mineral Hill is best described as a small polymetallic replacement deposit (19A of Cox and Singer, ) .
