A TRIASSIC OROGENIC GOLD MINERALIZATION EVENT IN THE PALEOPROTEROZOIC METAMORPHIC ROCKS: EVIDENCE FROM TWO TYPES OF RUTILE IN THE BAIYUN GOLD DEPOSIT, LIAODONG PENINSULA, NORTH CHINA CRATON

Economic Geology, 2022
Rutile grains often occur in different types of gold deposits, and their U-Pb ages have been widely used to determine the formation time of gold mineralization. However, the origin of rutile grains in the gold deposits remains controversial.

In situ chemical and isotopic analyses and element mapping of multiple-generation pyrite: Evidence of episodic gold mobilization and deposition for the Qiucun epithermal gold deposit in Southeast China

American Mineralogist, 2021
Gold deposits are often the result of complex mineralization and remobilization processes. Interpretation of bulk geochemical and sulfur isotope data of the gold deposits is frequently hampered by complex zoning in pyrite, which calls for in situ ...

Towards a universal model for orogenic gold systems: A perspective based on Chinese examples with geodynamic, temporal, and deposit-scale structural and geochemical diversity

Earth-Science Reviews, 2021
Although the term orogenic gold has become widely accepted over the past 20 years for disseminated- to lode-style gold deposits that formed in a variety of tectonic environments within convergent margins, models for orogenic gold systems have remained ...

Metallogenesis of the Hengjiangchong gold deposit in Jiangnan Orogen, South China

, 2020
The Hengjiangchong gold deposit is located in northeastern Hunan of the central Jiangnan Orogen, South China. Distribution of auriferous sulfide–calcite–quartz vein-type orebodies are controlled by NW-/WNW-trending ductile shear zones, and hosted in the ...
