Zircon Geochronology and Geochemistry of Orogenic Belts and Gold Deposits
This community investigates the age, origin, and tectonic history of continental crust and ore deposits, primarily using zircon dating and trace element analysis.
The work centers on determining the timing and conditions of rock formation and mineralization in major tectonic regions, particularly across China, the Tibetan Plateau, and Central Asia. Researchers frequently employ zircon U-Pb geochronology and isotope geochemistry to constrain the evolution of orogenic belts and the genesis of gold deposits. The analysis often involves detrital zircon populations, fluid inclusions, and rare earth element patterns to distinguish between different magmatic sources and tectonic settings. The focus is on understanding how continental crust has been built, modified, and enriched in metals over geological time, with a strong emphasis on the Early Cretaceous and other key periods of tectonic activity.
The largest share of the community's output is found in neodymium research, representing 20.7% of all neodymium research, and thorium research, representing 15.2% of all thorium research. Zirconium research also accounts for a significant portion, with 14.2% of all zirconium research appearing in this group.
The community comprises 89,793 papers, publishing most frequently in Geochimica et Cosmochimica Acta, Ore Geology Reviews, and Economic Geology.
Recent work continues to focus on the geochemical and geochronological characterization of specific geological units, such as the sources of lithium-rich granites and the evolution of drainage systems in Tibet. Other recent studies examine the role of sediment subduction in enriching mantle sources for rare earth elements and the mineral systems approach to clay deposits.
