Geology, Fluid Inclusion, and H–O–S–Pb Isotope Constraints on the Mineralization of the Xiejiagou Gold Deposit in the Jiaodong Peninsula

open access: yesGeofluids, Volume 2019, Issue 1, 2019., 2019
The Xiejiagou deposit is a representative medium‐sized gold deposit in Jiaodong the Peninsula, which contains gold reserves of 37.5 t. The orebodies are hosted in the Linglong biotite granite with a zircon LA‐ICP‐MS U–Pb age of 160.5 ± 1.3 Ma (N = 15, MSWD = 1.2) and are characterized by disseminated‐ or stockwork‐style ores.

Geology, Mineralogy, Fluid Inclusion, and H–O–S–Pb Isotope Constraints on Ore Genesis of the Keyue Sb–Pb–Zn–Ag Deposit in Southern Tibet

open access: yesGeofluids, Volume 2018, Issue 1, 2018., 2018
The Keyue deposit is a medium‐sized deposit similar to the Zhaxikang deposit within the North Himalayan Metallogenic Belt (NHMB). The ore formation can be divided into Pb–Zn mineralization (stages 1 and 2), Sb–Ag mineralization (stages 3 and 4), and Sb–Hg mineralization (stages 5 and 6).

Modelling Seismically Induced Mesothermal Goldfields along the Deep‐Rooted Cadillac‐Larder Lake Fault, Abitibi, Canada

open access: yesGeofluids, Volume 2018, Issue 1, 2018., 2018
Gold deposits are not uniformly distributed along major faults due to complex (and long‐debated) interactions between seismicity, hydrothermalism, and structural heterogeneities. Here, we use static stress modelling (SSM) to quantitatively investigate these interactions, by exploring the role of Cadillac‐Larder Lake Fault (CLLF) Archean seismicity in ...

Genesis of the Bairendaba Ag‐Zn‐Pb Deposit, Southern Great Xing’an Range, NE China: A Fluid Inclusion and Stable Isotope Study

open access: yesGeofluids, Volume 2017, Issue 1, 2017., 2017
The Bairendaba deposit is the largest Ag‐Zn‐Pb deposit in Inner Mongolia. Vein and disseminated ores occur in biotite‐plagioclase gneiss and quartz diorite along regional EW trending faults. Microthermometric data for H2O‐NaCl ± CH4 ± CO2 fluid inclusions record a decrease in homogenization temperature and salinity of ore‐forming fluids with time ...

The importance of mineralogical knowledge in the sustainability of artisanal gold mining: a mid-south Peru case [PDF]

open access: yes, 2019
Mineralogy and gold processing techniques from several mining areas of the Nazca-Ocoña gold belt, Mid-South Peru, were investigated to assess the efficiency of gold extraction methods in relation to their mineralogy.

Origin and Evolution of the Ore‐Forming Fluids in the Liyuan Gold Deposit, Central North China Craton: Constraints from Fluid Inclusions and H‐O‐C Isotopic Compositions

open access: yesGeofluids, Volume 2017, Issue 1, 2017., 2017
The Liyuan gold deposit is hosted within Archean basement metamorphic rocks and controlled by the NNE‐trending faults in the central North China Craton. The ore‐forming processes can be divided into three stages (early, middle, and late). Three types of primary fluid inclusions (FIs) are identified in the Liyuan, including pure carbonic, carbonic ...

Geochemistry, Paragenesis, and Wall‐Rock Alteration of the Qatruyeh Iron Deposits, Southwest of Iran: Implications for a Hydrothermal‐Metasomatic Genetic Model

open access: yesJournal of Geological Research, Volume 2014, Issue 1, 2014., 2014
The Qatruyeh iron deposits, located on the eastern border of the NW‐SE trending Sanandaj‐Sirjan metamorphic zone, southwest of Iran, are hosted by a late Proterozoic to early Paleozoic sequence dominated by metamorphosed carbonate rocks. The magnetite ores occurred as layered to massive bodies, with lesser amounts of disseminated magnetite and hematite‐
