An integrated mineral system model for the gold deposits of the giant Jiaodong province, eastern China

Earth-Science Reviews, 2020
The giant Jiaodong gold province, with more than 5000 t of proven gold resources, is unique in that its Mesozoic gold deposits are hosted in a Precambrian basement block.

Invisible Gold Paragenesis and Geochemistry in Pyrite from Orogenic and Sediment-Hosted Gold Deposits

Minerals (Basel, Switzerland), 2020
LA-ICPMS analysis of pyrite in ten gold deposits is used to determine the precise siting of invisible gold within pyrite, and thus the timing of gold introduction relative to the growth of pyrite and related orogenic events.

Parameters for the formation of orogenic gold deposits

Applied Earth Science: Transactions of the Institute of Mining and Metallurgy, 2019
Orogenic gold deposits are the main source of gold for humanity. These deposits formed from the Archaean to Phanerozoic at crustal depths of more than 4 km. The key parameters accounting for their formation remain under discussion.

A metasedimentary source of gold in Archean orogenic gold deposits

Geology, 2021
The sources of metals enriched in Archean orogenic gold deposits have long been debated. Metasedimentary rocks, which are generally accepted as the main metal source in Phanerozoic deposits, are less abundant in Archean greenstone belts and commonly ...

Metal remobilization from country rocks into the Jiaodong-type orogenic gold systems, Eastern China: New constraints from scheelite and galena isotope results at the Xiadian and Majiayao gold deposits

Ore Geology Reviews, 2021
Orogenic gold deposits in the Jiaodong Peninsula contain more than 5000 t of known gold resources. Precambrian metamorphic rocks and Mesozoic granite represent the main host rocks for these deposits, but gold deposition (∼120 Ma) is significantly younger

Multivariate statistical analysis of trace element compositions of native gold from orogenic gold deposits: Implication for mineral exploration

, 2021
The mineralogy and chemical composition of native gold from twenty-seven representative orogenic gold deposits were investigated using optical microscopy, electron probe microanalysis (EPMA), and laser ablation-inductively coupled plasma-mass ...
