Mineralogy and distribution of critical elements in the Sn–W–Pb–Ag–Zn Huanuni deposit, Bolivia [PDF]

, 2019
The polymetallic Huanuni deposit, a world-class tin deposit, is part of the Bolivian tin belt. As a likely case for a “mesothermal” or transitional deposit between epithermal and porphyry Sn types (or shallow porphyry Sn), it represents a case that ...

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

Geofluids, 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

Geofluids, 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

Geofluids, 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

Geofluids, 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 ...

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

Geofluids, 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 ...
