A new genetic model for the Triassic Yangyang iron-oxide-apatite deposit, South Korea: Constraints from in situ U-Pb and trace element analyses of accessory minerals
The Yangyang iron-oxide-apatite deposit in South Korea has undergone multiple episodes of igneous activity, deformation, hydrothermal alteration, and iron-oxide-apatite (IOA) mineralization. The iron orebodies occur as concordant- to discordant-layered lenticular or massive magnetite and/or magnetite-pyrite ores. The iron mineralization occurs along a N-S-trending shear zone within the Yangyang syenite, which experienced both early ductile and later brittle deformations. Alteration was caused...[Show more]
